Ubuntu 14.04 LTS / 14.10 : strongswan vulnerability (USN-2450-1)

Medium Nessus Plugin ID 80391


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


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.

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 strongswan-ike package.
