USN-2450-1: strongSwan vulnerability

5 January 2015

strongSwan could be made to crash if it received specially crafted network traffic.




Mike Daskalakis discovered that strongSwan incorrectly handled IKEv2
payloads that contained the Diffie-Hellman group 1025. A remote attacker
could use this issue to cause the IKE daemon to crash, resulting in a
denial of service.

Update instructions

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

Ubuntu 14.10
Ubuntu 14.04

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