** Description changed:
Hi!
The Aptcc backend in PackageKit saves the changelog to a predictable location
in /tmp. As packagekitd is running as root, bad people could just add a symlink
named like the file in /tmp (e.g. to /etc/shadow) to screw up the system.
I fixed this in Debian already, you might want to take the patch
(02_aptcc-changelog-random-dir.patch) from there and apply it to Precise, if
possible.
For Quantal, please merge/sync packagekit 0.7.4-4 from Debian Sid, which
contains the patch and some other improvements.
Cheers,
- Matthias

+ UPDATE: The same also applies for our Debconf handling. While the
changelog-issue is fixed, this issue is still valid for debconf sockets.
+ I therefore reopened this bug on Quantal and linked the Debian issue, which
will be fixed soon.
