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... ;-)
