Ubuntu 10.04 LTS / 12.04 LTS / 14.04 LTS / 14.10 : elfutils vulnerability (USN-2482-1)

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 :

Alexander Cherepanov discovered that libelf1 incorrectly handled
certain filesystem paths while extracting ar archives. An attacker
could use this flaw to perform a directory traversal attack on the
root directory if the process extracting the ar archive has write
access to the root directory.

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 libelf1 package.

Risk factor :

Medium / CVSS Base Score : 6.4
(CVSS2#AV:N/AC:L/Au:N/C:N/I:P/A:P)
CVSS Temporal Score : 5.3
(CVSS2#E:F/RL:OF/RC:ND)
