Ubuntu 8.04 LTS / 8.10 : sudo vulnerability (USN-722-1)

Ubuntu Security Notice (C) 2009-2016 Canonical, Inc. / NASL script (C) 2009-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

Harald Koenig discovered that sudo did not correctly handle certain
privilege changes when handling groups. If a local attacker belonged
to a group included in a 'RunAs' list in the /etc/sudoers file, that
user could gain root privileges. This was not an issue for the default
sudoers file shipped with Ubuntu.

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 sudo and / or sudo-ldap packages.

Risk factor :

Medium / CVSS Base Score : 6.9
(CVSS2#AV:L/AC:M/Au:N/C:C/I:C/A:C)
CVSS Temporal Score : 5.7
(CVSS2#E:F/RL:OF/RC:C)
Public Exploit Available : true
