high Nessus Plugin ID 146616

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The Asterisk project reports :

When re-negotiating for T.38 if the initial remote response was delayed just enough Asterisk would send both audio and T.38 in the SDP. If this happened, and the remote responded with a declined T.38 stream then Asterisk would crash.

Solution

Update the affected packages.
