I will not be updating. I have yet to see this mythic JavaScript exploit, and I see too many other ways I, as an end user, can be affected. I haven't even seen a proof of concept exploit that has the same conditions as in the wild. All the POC exploits seems to have been given some assistance in various ways (such as being given root perms or a preknown memory address). Does anybody have an example of this JavaScript exploit or any exploit that would work in the wild?
