Ubuntu 10.04 LTS / 11.10 / 12.04 LTS / 12.10 : xorg-server, xorg-server-lts-quantal vulnerability (USN-1803-1)

Low Nessus Plugin ID 66022


The remote Ubuntu host is missing one or more security-related patches.


It was discovered that the X.Org X server did not properly clear input events in certain circumstances. A local attacker with physical access could use this flaw to capture keystrokes.

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 xserver-xorg-core and / or xserver-xorg-core-lts-quantal packages.
