** Description changed:

- AppArmor profile weaknesses in Ubuntu. This bug will track the work
- needed to fix it.

- This is a continuation of bug #851986, except for PATH and shell
- scripts. Unfortunately, until we have proper environment filtering
- support in AppArmor, we will have to employ more bandaids--
- specifically, either eliminating Ux/sanitized helper on shell scripts or
- adjusting those shell scripts to explicitly set their PATH. The good
- news is that environment filtering is on the AppArmor roadmap, and it
- something we will be targeting in the future releases. I filed bug
- #1045985 to more easily track the progress of that work.
