Ubuntu 12.10 : gnome-screensaver vulnerability (USN-1716-1)

Ubuntu Security Notice (C) 2013-2016 Canonical, Inc. / NASL script (C) 2013-2016 Tenable Network Security, Inc.

Synopsis :

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

Description :

It was discovered that gnome-screensaver did not start automatically
after logging in. This may result in the screen not being
automatically locked after the inactivity timeout is reached,
permitting an attacker with physical access to gain access to an
unlocked session.

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 gnome-screensaver package.

Risk factor :

High / CVSS Base Score : 7.2

Family: Ubuntu Local Security Checks
