Ubuntu 12.04 LTS : xscreensaver vulnerability (USN-2789-1)

Low Nessus Plugin ID 86720


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


It was discovered that XScreenSaver incorrectly handled unplugging an external monitor. An attacker with physical access could use this flaw to gain access to a locked session.

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 xscreensaver package.
