CVE-2012-0949 was discovered to be incomplete. This update fixes the
problem.

Felix Geyer discovered that the Update Manager Apport hook incorrectly
uploaded certain system state archive files to Launchpad when
reporting bugs. This could possibly result in repository credentials
being included in public bug reports. (CVE-2012-0949).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
