Ubuntu 9.10 / 10.04 LTS : sudo vulnerability (USN-983-1)

Ubuntu Security Notice (C) 2010-2016 Canonical, Inc. / NASL script (C) 2010-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

Markus Wuethrich discovered that sudo did not always verify the user
when a group was specified in the Runas_Spec. A local attacker could
exploit this to execute arbitrary code as root if sudo was configured
to allow the attacker to use a program as a group when the attacker
was not a part of that group.

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 : 6.2
(CVSS2#AV:L/AC:H/Au:N/C:C/I:C/A:C)
