Ubuntu 12.04 LTS : openvpn vulnerability (USN-2368-1)

Ubuntu Security Notice (C) 2014-2016 Canonical, Inc. / NASL script (C) 2014-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

It was discovered that OpenVPN incorrectly handled HMAC comparisons
when running in UDP mode. If a remote attacker were able to perform a
man-in-the-middle attack, this flaw could possibly be used to perform
a plaintext recovery attack.

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 openvpn package.

Risk factor :

Low / CVSS Base Score : 2.6
(CVSS2#AV:N/AC:H/Au:N/C:P/I:N/A:N)
CVSS Temporal Score : 1.9
