Ubuntu 10.04 LTS / 12.04 LTS / 13.10 / 14.04 LTS : apt vulnerability (USN-2246-1)

Medium Nessus Plugin ID 76108


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


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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected apt package.
