Ubuntu Security Notice (C) 2011-2013 Canonical, Inc. / NASL script (C) 2011-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

Alexander Kurtz discovered that sudo would not prompt for a password
when a group was specified in the Runas_Spec. A local attacker could
exploit this to execute arbitrary code as the specified group if sudo
was configured to allow the attacker to use a program as this group.
The group Runas_Spec is not used in the default installation of
Ubuntu.

Solution :

Update the affected sudo and / or sudo-ldap packages.

Risk factor :

Medium / CVSS Base Score : 4.4
(CVSS2#AV:L/AC:M/Au:N/C:P/I:P/A:P)
