Ubuntu Security Notice (C) 2006-2016 Canonical, Inc. / NASL script (C) 2006-2016 Tenable Network Security, Inc.
The remote Ubuntu host is missing a security-related patch.
Marcus Meissner discovered a race condition in gdm's handling of the
~/.ICEauthority file permissions. A local attacker could exploit this
to become the owner of an arbitrary file in the system. When getting
control over automatically executed scripts (like cron jobs), the
attacker could eventually leverage this flaw to execute arbitrary
commands with root privileges.
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.
Update the affected gdm package.
