medium Nessus Plugin ID 28075

Synopsis

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

Description

It was discovered that xscreensaver did not correctly validate the return values from network authentication systems such as LDAP or NIS.
A local attacker could bypass a locked screen if they were able to interrupt network connectivity.

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.
