Synopsis

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

Description

The Asterisk project reports :

A memory leak occurs when an Asterisk pjsip session object is created and that call gets rejected before the session itself is fully established. When this happens the session object never gets destroyed. This then leads to file descriptors and RTP ports being leaked as well.

Solution

Update the affected package.
