Note: Versions mentioned in the description apply only to the upstream strongswan package and not the strongswan package as distributed by Ubuntu. See How to fix? for Ubuntu:16.04 relevant fixed versions and status.

In stroke_socket.c in strongSwan before 5.6.3, a missing packet length check could allow a buffer underflow, which may lead to resource exhaustion and denial of service while reading from the socket.
