Medium Nessus Plugin ID 103356

Synopsis

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

Description

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.
