critical Nessus Plugin ID 140314

Synopsis

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

Description

Version 5.9 contains security fix for L2TP clients and servers.
Insufficient validation of incoming L2TP control packet specially crafted by unauthenticated user might lead to unexpected termination of the process. The problem affects mpd versions since 4.0 that brought in initial support for L2TP. Installations not using L2TP clients nor L2TP server configuration were not affected.

Solution

Update the affected package.
