Binary package hint: apparmor

Description: Ubuntu 9.10
Release: 9.10
Package: apparmor
System: Linux tehcomputer 2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:05:01 UTC 2009 x86_64 GNU/Linux

The following will cause a null dereference and a "kernel oops".

Steps:
1. Generate an apparmor profile for empathy (I can send my apparmor profile via email)
2. Make sure empathy can load and no messages are reported in audit.
  (Make sure gnome-help isn't allowed to execute by keeping it absent from the apparmor profile)
3. Enforce the empathy apparmor profile
4. Load empathy until empathy UI opens
5. Set empathy profile to complain
6. In empathy, click Help->Contents
7. Verify that audit is sending out complain messages as gnome-help opens with empathy help contents
8. Run apparmor_parser -R /etc/init.d/usr.bin.empathy

Result:
1. Nov 4 16:47:21 tehcomputer kern: [76781.229046] BUG: unable to handle kernel NULL pointer dereference at 0000000000000068
