Ubuntu Security Notice USN-2450-1
January 05, 2015

strongswan vulnerability

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

- Ubuntu 14.10
- Ubuntu 14.04 LTS


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

Software Description:
- strongswan: IPsec VPN solution


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:
  strongswan-ike                  5.1.2-0ubuntu3.2

Ubuntu 14.04 LTS:
  strongswan-ike                  5.1.2-0ubuntu2.2

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