Ubuntu 8.04 LTS / 10.04 LTS / 11.04 / 11.10 / 12.04 LTS : sudo vulnerability (USN-1442-1)

Ubuntu Security Notice (C) 2012-2013 Canonical, Inc. / NASL script (C) 2012-2013 Tenable Network Security, Inc.


Synopsis :

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

Description :

It was discovered that sudo incorrectly handled network masks when
using Host and Host_List. A local user who is listed in sudoers may be
allowed to run commands on unintended hosts when IPv4 network masks
are used to grant access. A local attacker could exploit this to
bypass intended access restrictions. Host and Host_List are not used
in the default installation of Ubuntu.

Solution :

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

Risk factor :

High / CVSS Base Score : 7.2
(CVSS2#AV:L/AC:L/Au:N/C:C/I:C/A:C)
