Ubuntu 10.04 LTS / 10.10 / 11.04 / 11.10 : software-properties vulnerability (USN-1352-1)

medium Nessus Plugin ID 57763

Synopsis

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

Description

David Black discovered that Software Properties incorrectly validated server certificates when performing secure connections to download PPA GPG key fingerprints. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could be exploited to install altered package repository GPG keys.

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 python-software-properties package.
