Synopsis :

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

Description :

Asterisk project reports :

It is possible to enumerate SIP usernames when the general and
user/peer NAT settings differ in whether to respond to the port a
request is sent from or the port listed for responses in the Via
header.

When the 'automon' feature is enabled in features.conf, it is possible
to send a sequence of SIP requests that cause Asterisk to dereference
a NULL pointer and crash.
