FreeBSD : Asterisk -- multiple vulnerabilities (3c7d565a-6c64-11e0-813a-6c626dd55a41)

Synopsis :

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

Description :

The Asterisk Development Team reports :

It is possible for a user of the Asterisk Manager Interface to bypass
a security check and execute shell commands when they should not have
that ability. Sending the 'Async' header with the 'Application' header
during an Originate action, allows authenticated manager users to
execute shell commands. Only users with the 'system' privilege should
be able to do this.

On systems that have the Asterisk Manager Interface, Skinny, SIP over
TCP, or the built in HTTP server enabled, it is possible for an
attacker to open as many connections to asterisk as he wishes. This
will cause Asterisk to run out of available file descriptors and stop
processing any new calls. Additionally, disk space can be exhausted as
Asterisk logs failures to open new file descriptors.
