Asterisk Project Security Advisory - 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.
