strongswan vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.10
- Ubuntu 14.04 LTS
Summary:
strongSwan could be made to crash or run programs if it received specially
crafted network traffic.
Software Description:
- strongswan: IPsec VPN solution
Details:
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:
