Ubuntu 6.06 LTS / 8.04 LTS / 9.04 / 9.10 / 10.04 LTS : sudo vulnerability (USN-956-1)

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 :

Evan Broder and Anders Kaseorg discovered that sudo did not properly
sanitize its environment when configured to use secure_path (the
default in Ubuntu). A local attacker could exploit this to execute
arbitrary code as root if sudo was configured to allow the attacker to
use a program that interpreted the PATH environment variable.

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)
CVSS Temporal Score : 5.4
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : true
