CVE-2013-7294

Name of the Vulnerable Software and Affected Versions libreswan versions prior to 3.7

Description The issue allows remote attackers to cause a denial of service, resulting in a restart, by sending an IKEv2 I1 notification without a KE payload. This is due to a problem in the ikev2parent inI1outR1 function in pluto/ikev2 parent.c.

Recommendations For versions prior to 3.7, update to version 3.7 or later to resolve the issue. As a temporary workaround, consider restricting access to the ikev2parent inI1outR1 function until a patch is available.
