Ubuntu 8.04 LTS / 10.04 LTS / 11.04 / 11.10 / 12.04 LTS : apt update (USN-1475-1)

Ubuntu Security Notice (C) 2012-2013 Canonical, Inc. / NASL script (C) 2012-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

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.

Solution :

Update the affected apt package.

Risk factor :

High
