Ubuntu Security Notice USN-1414-1
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.
- aptdaemon - transaction based package management service
It was discovered that Aptdaemon incorrectly handled installing packages
without performing a transaction simulation. An attacker could possibly use
this flaw to install altered packages.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 11.10:
- python-aptdaemon 0.43+bzr697-0ubuntu1.2
- Ubuntu 11.04:
- python-aptdaemon 0.41+bzr661-0ubuntu0.2
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
