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

Low Nessus Plugin ID 78041


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


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.


Update the affected openvpn package.
