Ubuntu 11.10 / 12.04 LTS / 12.10 : apt vulnerability (USN-1762-1)

medium Nessus Plugin ID 65571

Synopsis

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

Description

Ansgar Burchardt discovered that APT incorrectly handled InRelease files. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could potentially be used to install altered packages.

This update corrects the issue by disabling InRelease file support completely. Please note that this update breaks third-party repositories that provide only a InRelease file and no separate Release and Release.gpg files. The default Ubuntu repositories do not use InRelease files.

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.

Solution

Update the affected apt package.
