Ubuntu Security Notice USN-2368-1
October 02, 2014

openvpn vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS


OpenVPN could be made to expose sensitive information over the network.

Software Description:
- openvpn: virtual private network software


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.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.04 LTS:
  openvpn                         2.2.1-8ubuntu1.3

In general, a standard system update will make all the necessary changes.
