medium Nessus Plugin ID 57707

Language:

Synopsis

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

Description

It was discovered that the X wrapper incorrectly checked certain console permissions when launched by unprivileged users. An attacker connected remotely could use this flaw to start X, bypassing the console permissions check.

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 xserver-xorg package.
