Ubuntu 9.10 / 10.04 LTS / 10.10 : sudo vulnerability (USN-1046-1)

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


Synopsis :

The remote Ubuntu host is missing 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.

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 : 4.4
(CVSS2#AV:L/AC:M/Au:N/C:P/I:P/A:P)
CVSS Temporal Score : 3.8
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : true
