2nd April, 2012
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.10
- Ubuntu 11.04
An attacker could trick Aptdaemon into installing altered packages.

without performing a transaction simulation. An attacker could possibly use
this flaw to install altered packages.
