Intel Responds to Security Research Findings
- brndnmtthws 9y ago> Contrary to some reports, any performance impacts are workload-dependent, and, for the average computer user, should not be significant and will be mitigated over time. Given the lack of any facts, evidence, or details in the press release, how is anyone supposed to take Intel seriously?
- mey 9y agoConsidering Intel's dominance in the server space, I don't anyone is worried about the average user here
- mintplant 9y agoI mean, I am. I have a really nice laptop that I'd rather not have to replace.
- ejcx 9y agoIf you have malicious applications running on your laptop you have bigger problems already...
- gpm 9y agoMalicious JS is fairly common on laptops... just see all the cryptominers.
- betterunix2 9y agoThe "put a big moat around it" approach to security should be put to rest. We isolate system processes and user accounts for good reason.
- tedunangst 9y agoMaybe wait until next week to decide if it needs replacing?
- thezilch 9y agoDevils advocate. Workload dependence... average user... not significant: A lot of users probably see "30%" and will assume the worst. There really isn't a lot of evidence of how much an average consumer will be affected. Pretty sure your average consumer isn't running pgbench all day. Hell, I'm willing to bargain 90% of servers (I really want to say more) are over-provisioned by 30% or more. Mitigated over time: Kernels are getting out safe patches ASAP, performance be damned. With more time to be careful, performance can be clawed back. And/or CPUs are upgrade and features such as PCID mitigate perf losses.
- teilo 9y agoThe problem is that "average users" pointedly does not include server and DB admins. I don't know about anyone else, but that's what I'm sweating over. We already know high I/O is what takes the biggest hit. I want to know what kind of a hit I can expect on our MSSQL VMs, and I am pretty sure the answer is not "minimal."
- deadshift 9y agoIf you're running SQL in a VM ... I'm pretty sure I know how to improve your performance by 30%.
- teilo 9y agoIf you mean run on bare metal, not happening, due to MSFT's outrageous core pricing model. They force you to license every core available to the OS, whether you need the capacity or not. Running in a VM is the only way of getting around that requirement. If you mean run something other than MSSQL — also not happening. Vendor lock in.
- jsteemann 9y agoGiven the potential slowdowns to be expected by the kernel fixes, I am not expecting a jolly January. I work for a database vendor.
- CiPHPerCoder 9y ago> Intel is committed to the industry best practice of responsible disclosure of potential security issues No, the industry best practice is coordinated disclosure. The term "responsible disclosure" is a misnomer that we'd be far better off if we, as a society, stopped using it. https://adamcaudill.com/2015/11/19/responsible-disclosure-is-wrong/ https://adamcaudill.com/2015/11/19/responsible-disclosure-is...
- tedunangst 9y agoDo you think the executive speculation has been well coordinated? :)
- alacombe 9y agoThis is not a security report, this is PR. Among other things, it implies, without explicitly naming them, that AMD, ARM and OS vendors are being directly affected while most information out there point out it's merely an Intel issue.
- bjtitus 9y agoIt does explicitly name them: > Intel is committed to product and customer security and is working closely with many other technology companies, including AMD, ARM Holdings and several operating system vendors, to develop an industry-wide approach to resolve this issue promptly and constructively.
- mynameisvlad 9y agoI think what the parent comment means is that they're explicitly named, but not explicitly called out as being affected, just heavily implied.
- mappu 9y agoSome ARM cores are genuinely implicated in this: https://news.ycombinator.com/item?id=16058454 https://news.ycombinator.com/item?id=16058454
- robin_reala 9y ago> Intel and other vendors had planned to disclose this issue next week when more software and firmware updates will be available. So coordinated patches to hit next week then.
- jaydestro 9y agothis is a denial from PR and a poor one at that.
- rpns 9y agoIt comes across as fairly defensive. Presumably the statement was hastily put together, but it's not really the tone you want to strike when you have a lot of worried customers wondering what is going on. > Intel believes its products are the most secure in the world and that, with the support of its partners, the current solutions to this issue provide the best possible security for its customers. A rather bizarre statement of nothingness, and also an odd thing to say in a statement that just named AMD and ARM. > Contrary to some reports, any performance impacts are workload-dependent, and, for the average computer user, should not be significant and will be mitigated over time. It's interesting to note what it doesn't say – as it would seem to imply that for some workloads the performance impact will be significant.
- ovao 9y ago> A rather bizarre statement of nothingness, and also an odd thing to say in a statement that just named AMD and ARM. Particularly bizarre considering the use of "believes". If Intel disbelieved that their own products are the best in any particular respect, that might actually warrant a press release on its own.
- qubex 9y ago“Workload dependent” clearly implies (despite the spin they are trying to put on it) that some users will be worse off than others. What isn’t my at all clear (to me) is what they mean by ”will be mitigated over time”. Are they implying that when we buy new professors (from them) there’ll be a hardware fix that won’t require the performance-sapping patch? Quoting ARM and AMD is really a bit pathetic too, IMHO, especially if it turns out that AMD chips are immune to the flaw.
- rbanffy 9y agoWouldn't it be wonderful if we could buy the latest Xeons at a 30% discount? ;-)
- bkeroack 9y agoThat's why they're the dominant player. Because even when a horrible defect is exposed people still desire the product over the competition.
- aceofspad4s 9y agoThey would have to screw up really bad for people to go to AMD. I think that may never happen.
- BoorishBears 9y agoNot disagreeing, but why do you say that?
- rbanffy 9y agoPeople who need to get absolutely the most bang for the buck have no ties to any given supplier. Cray deployed one of the first Opteron-based supercomputers. Intel got lots of datacenter business simply by having a better (as in "better suited to our demands") product than anyone else in the segment. AMD has a short time window to make some large sales. They have until Intel ships a microcode fix or a new line of processors.
- AsyncAwait 9y ago> They have until Intel ships a microcode fix Sounds like microcode fix isn't possible.
- rbanffy 9y agoThen the next generation it is. It's a 5-30% performance boost without even a major change. :-(
- thg 9y ago> Intel believes its products are the most secure in the world https://security-center.intel.com/advisory.aspx?intelid=INTEL-SA-00086&languageid=en-fr https://security-center.intel.com/advisory.aspx?intelid=INTE...
- aceofspad4s 9y ago"The most secure in the world" does not mean "flawless". Thinking like that is pretty dangerous (and silly)
- arghwhat 9y agoTrue, but no one claimed that. We are, however, claiming that Intel is not the most secure in the world. This, prior issues as linked, Intel ME, tons of undocumented instructions—some which mess up the system—, etc.
- thg 9y agoI haven't seen any articles about AMD PSP security vulnerabilities yet, but there's a new one about IME every other month. If Intel truly is the most secure in the world, why are their CPUs riddled with security bugs big enough to drive trains through (IME has de facto become a integral part of Intel CPUs) and where are the news about non-Intel CPUs with similar bugs?
- betterunix2 9y agoNo, but it does mean more secure than anything else, which is pretty doubtful. Competitors to x86 have always had an advantage as far as security goes; then there is the ME mess; and now we have this latest bug. Nobody expects perfection, but Intel is not "most secure in the world" by any stretch.
- deleted 9y ago[deleted]
- rhema 9y ago>Recent reports that these exploits are caused by a “bug” or a “flaw” and are unique to Intel products are incorrect. From the English, this report makes it seems like there was no bug and no flaw. However, they say that ((bug || flaw) && only_intel) is false, but I have seen that AMD was not impacted. Seems like this is a bug or flaw, since they are addressing it soon. They make it seem like everyone should be working in the same boat to address this, but they are just trying to un-distance themselves from their competition.
- bonzini 9y ago> since they are addressing it soon. They make it seem like everyone should be working in the same boat to address this I can assure you that indeed "everyone is working in the same boat to address this", and has been doing so for months, across multiple OS and processor vendors. It's already public that Microsoft and Apple have also implemented page table isolation, and certainly Intel didn't name-drop AMD and ARM carelessly in the press release.
- lettergram 9y ago> and certainly Intel didn't name-drop AMD and ARM carelessly in the press release. I'm sure it wasn't careless, but they are (from all accounts I have read) blatantly lying. Intel isn't known for above board practices. They will do what it takes to win - period. Name dropping their competitors (to me), honestly shows me how dire of a situation this is. If it wasn't, they wouldn't feel the need to defend themselves and say, "well look at everyone else".
- kunday 9y agoAccording to project zero report, a lot more than intel CPU's are affected by this issue. See relavant HN post here "These vulnerabilities affect many CPUs, including those from AMD, ARM, and Intel, as well as the devices and operating systems running them." https://news.ycombinator.com/item?id=16065845 https://news.ycombinator.com/item?id=16065845
- ejcx 9y agoLots of people being critical of this response. I think it's pretty good, and have been on the disclosing side of this equation many times. Admits responsibility and says their current course of action (working with key stakeholders). Addresses concerns of the workaround. Has a timeframe for future updates. Has a call to action for what you should be doing next. To those of you pointing out that this is PR, you're right but that's not a problem... Short and sweet and has it all. If anything, it is a day late but monstrous organizations probably had a lot of bureaucracy to cut through. People are so reactionary and quick to throw any company with a security issue under the bus, without ever having been on the other side of the table. The reality is issues happen to everyone and Intel wants to fix it.
- davesque 9y agoI do agree that there are passages in this press release that are totally justified e.g. their calling attention to the fact that other processor vendors have probably been incorporating this flaw into their designs for a while. However, their seemingly innocent mentioning of AMD as being a vendor with which they are coordinating to resolve this issue appears to unfairly (and probably deliberately) implicate AMD in all of this. I feel this was an attempt to divert attention to their competitor even though their competitor's products don't suffer from this problem. I'm guessing their marketing department gave this a once over.
- 2trill2spill 9y ago> their calling attention to the fact that many other processor vendors have been incorporating this flaw into their designs for while. You have a source for this claim? Because besides for Intel's press release I can't find any evidence that other manurfacture's processors are vulnerable to this bug.
- cjbprime 9y agoThe mitigation (KAISER) is being enabled for ARM as well as Intel x86 in the Linux kernel.
- electic 9y agoThis is a good time to bring up Intel ME. It is a black box and has already proven to have security issues. There maybe be more we do not know of. This paging flaw is accidental however Intel ME is designed to have unfettered control over all parts of the machine. If Intel really believed in making secure products and believed in secure computing, they would remove Intel ME.
- AshleysBrain 9y ago> Intel believes these exploits do not have the potential to corrupt, modify or delete data. Reading from kernel memory [edit: from unprivileged apps] is still a severe security issue though, right? This sounds like they're trying to downplay that hard, especially with the "operating as designed" phrase. > Recent reports that these exploits are caused by a “bug” or a “flaw” [Unprivileged] reading from kernel memory is something of a flaw, no? Fair point about not being Intel specific though. > any performance impacts are workload-dependent, and, for the average computer user, should not be significant Hearing echos of Intel's early FDIV response along the lines of "the average computer user doesn't need perfectly accurate division"... > However, Intel is making this statement today because of the current inaccurate media reports. This and similar sentences has a strange tone to me, it sounds almost grumpy. I guess it got rushed out.
- qubex 9y agoI’m with you that this is corporate-speak panicked PR damage containment at its finest, but reading from kernel memory is only a flaw if you aren’t the kernel. ;)
- AshleysBrain 9y agoHaha good point! That's what I meant of course :) edited for clarity.
- aneutron 9y ago> Reading from kernel memory is something of a flaw, no? Fair point about not being Intel specific though. Well the concept is not, but the company who's processors run most of the worlds' databases was PoC'ed, so ....
- ghrifter 9y agoSource please?
- blattimwind 9y ago
- 2trill2spill 9y ago> Recent reports that these exploits are caused by a “bug” or a “flaw” and are unique to Intel products are incorrect. Isn't the quote above which is from the Intel press release a blatant lie? All the articles I have seen say this only affects Intel processors. Not AMD processors nor, ARM, MIPS, SPARC or PowerPC chips. Did I miss something or is Intel lying in it's press release.
- thehardsphere 9y agoWe won't know until we know what the actual bug is. All we know is that people are writing patches for Intel chips, and what those patches do. It's very possible that other processors are affected by the same issue in some different way that doesn't require this set of patches to mitigate.
- betterunix2 9y agoWe know that AMD is not affected: https://lkml.org/lkml/2017/12/27/2 https://lkml.org/lkml/2017/12/27/2
- eropple 9y agoWe know that people think that AMD is not affected by this permutation of the attack. Intel may know differently; I'd withhold sweeping claims.
- cjbprime 9y agoYou think Intel considers AMD vulnerable while AMD considers itself not vulnerable? That's quite an assumption to ask of us.
- tedunangst 9y agoWould not be the first time vendor X knows vendor Y is vulnerable even as vendor Y denies it.
- mannykannot 9y agoInteresting use of language: 'Recent reports that these exploits... are unique to Intel products are incorrect... Intel is committed to product and customer security and is working closely with many other technology companies, including AMD...' Someone new to the issue might think AMD also has this problem. Similarly (replacing the first elision in the above quote): 'Recent reports that these exploits are caused by a “bug” or a “flaw”... are incorrect.' So, working just the way you want it to, eh, Intel? But then, why would you describe them as exploits?
- thezilch 9y agoNot defending Intel here, but devils advocate... You will find many clients asking how to disable, for example, the Linux patch. Linux is releasing with a flag to disable it, so there is some merit. Why would you want that? There are a lot of times you trust everything running on your box and don't need to take the perf hit. Intel (and possibly other archs/families) found a perf win that ends up having security implications. A perf nonetheless. If you're willing to bet on your userspace not reading kernel pages, does Intel have a feature for you!
- mannykannot 9y agoIntel is certainly entitled to make and promulgate an objective assessment of the impact of the problem, but a problem is still a problem even if it doesn't affect everyone.
- thezilch 9y agoWho says they won't? The issue is embargoed, but that's, as usual, not keeping everyone from speculating. That's fine too, but also realize the layman (even people in this thread) is getting pummeled with ideas like "my new laptop is going to be 30% slower tomorrow; WTF!!!"
- mannykannot 9y ago> Who says they won't? Not me. My comments are restricted to certain things Intel did choose to say. And as you are concerned about rumor and disinformation, I cannot imagine you are pleased with Intel's insinuation that AMD processors are also affected. UPDATE: It seems AMD may be being misleading in this case...
- baq 9y agoJudging by the comments here, most people are so outraged that they only read the first and last paragraph before wielding pitchforks. Please at least read it whole.
- myth_buster 9y agoIntel believes these exploits do not have the potential to corrupt, modify or delete data. Followed by... Check with your operating system vendor or system manufacturer and apply any available updates as soon as they are available. This press release is a minefield. There are whole paragraphs devoted to say nothing.
- vhold 9y agoSomebody please correct me if I'm wrong, but I believe they're basically saying "These exploits do have the potential to read data."
- int0x80 9y agoThere are not saying it explicitly, which they should.
- IshKebab 9y agoYeah, sort of "Don't worry I'm not going to shoot you in the torso, arms or legs."
- PeterisP 9y agoThey are - literally the sentence before that states "methods that, when used for malicious purposes, have the potential to improperly gather sensitive data from computing devices that are operating as designed".
- jsteemann 9y agoYep, seems to me they put much work into the statement "the exploits do not have the potential to corrupt, modify or delete data.". Which leaves open if (that?) reading of data is possible. And as this is not explicitly denied, we have to fear this is exactly what is possible.
- IshKebab 9y agoYes as far as we know it allows user-space code to read kernel memory, but not modify it. It affects Intel but not AMD according to them (not sure why Intel says otherwise). Details in this blog post from several months ago: https://cyber.wtf/2017/07/28/negative-result-reading-kernel-memory-from-user-mode/ https://cyber.wtf/2017/07/28/negative-result-reading-kernel-... They didn't get it to work but obviously someone else has.
- resoluteteeth 9y agoSeriously? Their response is "It's not fair! ARM made the same mistake so you can't blame us!"?
- valuearb 9y agohttps://www.youtube.com/watch?v=pdFl__NlOpA https://www.youtube.com/watch?v=pdFl__NlOpA
- monocasa 9y agoDo we know the actual bug yet? I sort of assumed it was a timing attack on KASLR rather than a leak of traditional kernel data. Although I guess that there would have been cheaper mitigations like mapping an empty page to all of the other KASLR slots rather than doing a full world switch in that case...
- thehardsphere 9y agoActual information about the bug itself is still embargoed. Most people are assuming it's the attack you suggest based on recent commits, but it's a guess.
- AshleysBrain 9y agoIt's true nobody knows what the actual bug is, but I was working with what Ars Technica described: "If the problem were just that it enabled the derandomization of ASLR, this probably wouldn't be a huge disaster... The industry reaction... suggests that it's not just ASLR that's defeated and that a more general ability to leak information from the kernel has been developed." https://arstechnica.com/gadgets/2018/01/whats-behind-the-intel-design-flaw-forcing-numerous-patches/ https://arstechnica.com/gadgets/2018/01/whats-behind-the-int...
- monocasa 9y agoI guess I've stopped reading security articles by Peter Bright ever since he spent a whole series of articles shitting on project zero for disclosing vulnerabilities after the 90 day disclosure window when Microsoft had just been sitting on the bug. https://arstechnica.com/information-technology/2015/01/google-drops-more-windows-0-days-somethings-gotta-give/ https://arstechnica.com/information-technology/2015/01/googl...
- klt0825 9y agoBigger than KASLR it seems. https://twitter.com/brainsmoke/status/948561799875502080 https://twitter.com/brainsmoke/status/948561799875502080 Not good.
- 9y ago
- dmitriid 9y agoCorporate-speak -> human-speak: - Yes, the flow/bug exists - We don't yet know if it can be successfully exploited at scale. - It's quite possible that other CPU designs are affected as well, we don't have concrete data though. AMD and ARM have already started looking into the issue. - Patches will be coming from as many manufacturers and as many OS-vendors as we can convince this is serious on a short notice. - The patches do affect performance, often significantly, but there's nothing we can do in such a short period of time. We can only hope we can come up with better solutions down the line.
- cesarb 9y ago> Recent reports that these exploits are caused by a “bug” or a “flaw” and are unique to Intel products are incorrect. A possible reading of "not a bug or a flaw" could be "works as designed", or better, "works according to the spec". The spec probably never considered cache timing side-channels (if that's what the issue is) as something to be defended against.
- Havoc 9y agoWhat a strange response. >many types of computing devices — with many different vendors’ processors Really? Like who?
- bjornedstrom 9y agoThis is probably one of the poorest and most defensive PR pieces I've read from a company in a long time, and it does not really make me sympathetic to them at all. > Intel and other technology companies have been made aware of new security research describing software analysis methods that, when used for malicious purposes, have the potential to improperly gather sensitive data from computing devices that are operating as designed. Intel believes these exploits do not have the potential to corrupt, modify or delete data. This is deceptive. It very quickly acknowledge the confidentiality aspect, but then claims that is "operating as designed" and then immediacy try to damage control by pointing out what the exploits cannot do (corrupt/modify/delete). > Recent reports that these exploits are caused by a “bug” or a “flaw” and are unique to Intel products are incorrect. Based on the analysis to date, many types of computing devices — with many different vendors’ processors and operating systems — are susceptible to these exploits. This is deceptive. In the first sentence it combines two statements: 1) bug/flaw in Intel products and 2) that it is unique to Intel. In the rest of the paragraph it then claims that the previous statements are incorrect, but only addressing the second point. > Intel is committed to product and customer security and is working closely with many other technology companies, including AMD, ARM Holdings and several operating system vendors, to develop an industry-wide approach to resolve this issue promptly and constructively. Intel has begun providing software and firmware updates to mitigate these exploits. Contrary to some reports, any performance impacts are workload-dependent, and, for the average computer user, should not be significant and will be mitigated over time. This is deceptive. It immediately mentions AMD to give the impression that AMD also suffer from the problem. It then goes on with a straw man about performance impacts ("contrary to some reports"). And then mentions "average computer user" whereas the real problem is obviously not average computer users. Again, deceptive.
- Nition 9y agoYeah, I had to read the “bug” or “flaw” part twice to be sure they're not saying it isn't a bug or flaw, they're only saying it isn't unique to Intel. And then as you say, they immediately mention AMD to imply that everyone has the issue, but they also avoid actually saying that. Your excellent analysis of what they're really saying reminds me of user thaumaturgy's analysis of Adancing Our Amazing Bet[1]. [1] https://news.ycombinator.com/item?id=12793033 https://news.ycombinator.com/item?id=12793033
- cyberpimp 9y agoThe reports are trickling in that Mossad has already exploited this security flaw to their advantage. Seems like the "flaw" may have been a backdoor designed by someone from their Haifa operations.
- cthalupa 9y agoYou have created a new account that only has anti-Intel and anti-Israel comments. Seems like you have some bias here. Source?
- matt4077 9y agoPlease don't spread conspiracy theories, especially not those with an undercurrent of antisemitism. At least not without links to these "reports".
- colanderman 9y ago> Intel believes these exploits do not have the potential to corrupt, modify or delete data. No, but they do have the potential for privilege escalation or credential exfiltration, which in turn do grant the potential to corrupt, modify and delete data.
- mabbo 9y ago> Based on the analysis to date, many types of computing devices — with many different vendors’ processors and operating systems — are susceptible to these exploits. Yes, many. Not your biggest competitor though, AMD. They're fine. And that may be the point you're trying to downplay here. > Intel believes its products are the most secure in the world Again, your biggest competitor, AMD, does not have this flaw. So precisely how is Intel the 'most secure in the world' if your biggest competitor is more secure than you? The title of this post should be 'Intel PR Responds to Security Research Findings'.
- mistercow 9y agoIt's always interesting when you see a damage control statement that basically boils down to "contrary to what you may have heard, <exactly the same caveats you've already heard>". It's a subtle kind of straw man, where you reassure your audience by listing the same mitigating facts they've already heard, but act as if those facts have been previously omitted. I guess the goal is to produce the affect of reassurance when you don't actually have any substantive reassurance to offer. I wonder if this works, in general? My sense is that it always smells like bullshit, but I wouldn't necessarily recall instances where it didn't.
- wasx 9y agoWow what a deceptive defensive response by intel. Nobody is concerned about data being deleted, it's the unprivileged access thats the issue here.
- smcleod 9y agoWhat a scummy, dishonest response. - Saying it's not a 'bug' or 'flaw' = lie. - Cold naming AMD and ARM in the post, I'm certain not just to throw their names in the ring but also for SEO ranking and relationships. - Failing to address the root cause, how it came to be and provide other technical references. And let's not forget - Intel's CEO sold his stock. -- * Note: "AMD chips are affected by some but not all of the vulnerabilities. AMD said that there is a "near zero risk to AMD processors at this time." British chipmaker ARM told news site Axios prior to this report that some of its processors, including its Cortex-A chips, are affected." - http://www.zdnet.com/article/security-flaws-affect-every-intel-chip-since-1995-arm-processors-vulnerable/ http://www.zdnet.com/article/security-flaws-affect-every-int...

- runesoerensen 9y agoProject Zero has published a detailed writeup on this. It's worth noting (in the context of Intel's response) that the P0 post confirms that AMD and ARM CPUs are also affected: "Variants of this issue are known to affect many modern processors, including certain processors by Intel, AMD and ARM. For a few Intel and AMD CPU models, we have exploits that work against real software. We reported this issue to Intel, AMD and ARM on 2017-06-01" https://googleprojectzero.blogspot.com/2018/01/reading-privileged-memory-with-side.html https://googleprojectzero.blogspot.com/2018/01/reading-privi...

- mrmondo 9y agoOh god, it's got a logo: https://meltdownattack.com https://meltdownattack.com "Which systems are affected by Meltdown? Desktop, Laptop, and Cloud computers may be affected by Meltdown. More technically, every Intel processor which implements out-of-order execution is potentially affected, which is effectively every processor since 1995 (except Intel Itanium and Intel Atom before 2013). We successfully tested Meltdown on Intel processor generations released as early as 2011. Currently, we have only verified Meltdown on Intel processors. At the moment, it is unclear whether ARM and AMD processors are also affected by Meltdown. Which systems are affected by Spectre? Almost every system is affected by Spectre: Desktops, Laptops, Cloud Servers, as well as Smartphones. More specifically, all modern processors capable of keeping many instructions in flight are potentially vulnerable. In particular, we have verified Spectre on Intel, AMD, and ARM processors."
- quadyeast 9y ago"Recent reports that these exploits are caused by a “bug” or a “flaw” and are unique to Intel products are incorrect." The 'and' in this sentence makes this assertion correct and is very deceptive.
