Pipe it to bash? game over
Pipe it to less/more? Better hope your distro keeps those patched
Open the file in a browser or PDF reader? Hey, look at all this shiny new attack surface!
- layer8 4mo agoHow do you set up the sandbox without having downloaded anything from the internet? I guess there’s still places where you can buy Linux CDs.
- inigyou 4mo agoWell yeah, that's true for any sandbox. If you pipe stuff outside of the sandbox, outside of any sandbox, and run it there, then you're not running it in a sandbox.
- swiftcoder 4mo agoRight, but nobody actually uses curl as the end destination, right? You use it to download something so that you can run another tool on it. And as such, you need to already be sandboxing the tool (since it processes untrusted data you received over the internet).
- inigyou 4mo agoHow would sandboxing curl help with vulnerabilities in your pdf reader?
- swiftcoder 4mo agoObviously, you need to sandbox all tools in the chain that handles untrusted data. This is security 101 stuff
- inigyou 4mo agoDo you sandbox the sandbox? When do you stop?
- niij 4mo agocurl is not anti-virus.
