Ubuntu 14.04 LTS : strongSwan vulnerability (USN-2450-1)

high Nessus Plugin ID 80391

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-2450-1 advisory.

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.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
