files with incorrect permissions when upgrading releases. A local user
could possibly use this to read repository credentials.
(CVE-2012-0948)

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).

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."
