Ubuntu 14.10 : autofs vulnerability (USN-2579-1)

Ubuntu Security Notice (C) 2015-2016 Canonical, Inc. / NASL script (C) 2015-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

It was discovered that autofs incorrectly filtered environment
variables when using program maps. When program maps were configured,
a local user could use this issue to escalate privileges.

This update changes the default behaviour by adding a prefix to
environment variables. Sites using program maps will need to adapt to
the new variable names, or revert to the previous names by using a new
configuration option called FORCE_STANDARD_PROGRAM_MAP_ENV.

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 autofs package.

Risk factor :

Medium / CVSS Base Score : 4.4
(CVSS2#AV:L/AC:M/Au:N/C:P/I:P/A:P)
CVSS Temporal Score : 3.7
(CVSS2#E:U/RL:U/RC:ND)
Public Exploit Available : false
