Ubuntu alert USN-1475-1 (apt)
========================================================================== Ubuntu Security Notice USN-1475-1 June 15, 2012 apt update ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 12.04 LTS - Ubuntu 11.10 - Ubuntu 11.04 - Ubuntu 10.04 LTS - Ubuntu 8.04 LTS Summary: APT now more thoroughly verifies imported keyrings. Software Description: - apt: Advanced front-end for dpkg Details: Georgi Guninski discovered that APT relied on GnuPG argument order and did not check GPG subkeys when validating imported keyrings via apt-key net-update. While it appears that a man-in-the-middle attacker cannot exploit this, as a hardening measure this update adjusts apt-key to validate all subkeys when checking for key collisions. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 12.04 LTS: apt 0.8.16~exp12ubuntu10.1 Ubuntu 11.10: apt 0.8.16~exp5ubuntu13.4 Ubuntu 11.04: apt 0.8.13.2ubuntu4.5 Ubuntu 10.04 LTS: apt 0.7.25.3ubuntu9.12 Ubuntu 8.04 LTS: apt 0.7.9ubuntu17.5 In general, a standard system update will make all the necessary changes.
