Low Nessus Plugin ID 21433


The remote FreeBSD host is missing a security-related update.


James Yonan reports :

If two or more client machines try to connect to the server at the same time via TCP, using the same client certificate, and when
--duplicate-cn is not enabled on the server, a race condition can crash the server with 'Assertion failed at mtcp.c:411'
