Detail

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.

Ubuntu 14.10:
