USN-1385-1: APT vulnerability

Releases

• Ubuntu 11.10
• Ubuntu 11.04

Packages

• apt - Advanced front-end for dpkg

Details

Simon Ruderich discovered that APT incorrectly handled repositories that
use InRelease files. The default Ubuntu repositories do not use InRelease
files, so this issue only affected third-party repositories. If a remote
attacker were able to perform a machine-in-the-middle attack, this flaw could
potentially be used to install altered packages.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 11.10

• apt - 0.8.16~exp5ubuntu13.2

Ubuntu 11.04

• apt - 0.8.13.2ubuntu4.4

In general, a standard system update will make all the necessary changes.
