Ubuntu 11.04 : gdm vulnerability (USN-1142-1)

Ubuntu Security Notice (C) 2011-2016 Canonical, Inc. / NASL script (C) 2011-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

Henne Vogelsang discovered that under certain PolicyKit
configurations, GDM could be made to launch a browser. A local
attacker could exploit this to gain access to files with the
privileges of the gdm user. PolicyKit is not configured in this manner
in Ubuntu by default.

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 gdm package.

Risk factor :

High / CVSS Base Score : 7.2
(CVSS2#AV:L/AC:L/Au:N/C:C/I:C/A:C)
