Ubuntu 14.04 LTS / 16.04 LTS : cvs vulnerability (USN-3399-1)

high Nessus Plugin ID 102680

Synopsis

The remote Ubuntu host is missing a security update.

Description

Hank Leininger discovered that cvs did not properly handle SSH for remote repositories. A remote attacker could use this to construct a cvs repository that when accessed could run arbitrary code with the privileges of the user.

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 cvs package.
