Ubuntu 10.04 LTS / 11.04 / 11.10 / 12.04 LTS : software-properties vulnerability (USN-1588-1)

High Nessus Plugin ID 62387


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


It was discovered that the apt-add-repository tool incorrectly validated PPA GPG keys when importing from a keyserver. 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.


Update the affected python-software-properties package.
