So, what exactly are the security risks I get into by opening local PDF files (generated by reputable sources, such as governments) with acroread in Linux? Can they be avoided or limited with a good AppArmor profile?
I don't know about the exact security risks - maybe someone from the security team knows more details. With an AppArmor profile, you can make sure that acroread only reads *.pdf files and doesn't read or modify random files on your disk. You can also forbid networking - but this doesn't sound too useful when you need to submit a form online ;-) Anyway, I'll attach my AppArmor profile for acroread. It's not as tight as it could be (and I'll probably do some changes to it now that I know acroread won't get security updates anymore), but it's a good start. Be warned that you will need to change it - for example I'm quite sure your home directory is not /home/cb/ ;-) Note: the profile only covers the binary, not the wrapper script.
If the danger is in the Firefox plugin, for instance, that can be removed with less trouble.
Indeed, just zypper rm acroread-browser-plugin I'd strongly recommend to do that (guess who split off this subpackage, and why... ;-) Regards, Christian Boltz -- <coolo> Ilmehtar: in rails you don't javascript, you jquery <coolo> or even worse, you coffee <ancor> Ilmehtar: coolo is right.
