Ubuntu 11.10 / 12.04 LTS : aptdaemon vulnerability (USN-1666-1)
Medium Nessus Plugin ID 63286
SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionIt was discovered that Aptdaemon 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.
SolutionUpdate the affected aptdaemon package.
