USN-2246-1: APT vulnerability
Ubuntu Security Notice USN-2246-1
17th June, 2014
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.04 LTS
- Ubuntu 13.10
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS
An attacker could trick APT into installing altered source packages.
- apt - Advanced front-end for dpkg
Jakub Wilk discovered that APT did not correctly validate signatures when
downloading source packages. If a remote attacker were able to perform a
man-in-the-middle attack, this flaw could potentially be used to install
altered source packages.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 14.04 LTS:
- apt 1.0.1ubuntu2.1
- Ubuntu 13.10:
- apt 0.9.9.1~ubuntu3.2
- Ubuntu 12.04 LTS:
- apt 0.8.16~exp12ubuntu10.17
- Ubuntu 10.04 LTS:
- apt 0.7.25.3ubuntu9.15
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.
