Ubuntu 5.10 / 6.06 LTS : gdm vulnerability (USN-293-1)

Ubuntu Security Notice (C) 2006-2013 Canonical, Inc. / NASL script (C) 2007-2013 Tenable Network Security, Inc.


Synopsis :

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

Description :

If the admin configured a gdm theme that provided an user list, any
user could activate the gdm setup program by first choosing the setup
option from the menu, clicking on the user list and entering his own
(instead of root's) password. This allowed normal users to configure
potentially dangerous features like remote or automatic login.

Please note that this does not affect a default Ubuntu installation,
since the default theme does not provide an user list. In Ubuntu 6.06
you additionally have to have the 'ConfigAvailable' setting enabled in
gdm.conf to be vulnerable (it is disabled by default).

Ubuntu 5.04 is not affected by this flaw.

Solution :

Update the affected gdm package.

Risk factor :

Low / CVSS Base Score : 3.7
(CVSS2#AV:L/AC:H/Au:N/C:P/I:P/A:P)
