           Version: stable grimoire
          Platform: All

            Status: NEW
          Severity: normal
          Priority: P2

Asterisk-addons version 1.4.7 fixes the following vulnerability in the ooh323
channel driver:
http://downloads.digium.com/pub/security/AST-2008-009.html (CVE-2008-2543)

Description:
The ooh323 channel driver provided in Asterisk Addons used a TCP connection to
pass commands internally. The payload of these packets included addresses of
memory which were to be freed after the command was processed. By sending
arbitrary data to the listening TCP socket, one could cause an almost certain
crash since the command handler would attempt to free invalid memory. This
problem was made worse by the fact that the listening TCP socket was bound to
whatever IP address was specified by the "bindaddr" option in ooh323.conf
