Asterisk Project Security Advisory - If a compound RTCP packet is received containing more than one report (for example a Receiver Report and a Sender Report) the RTCP stack will incorrectly store report information outside of allocated memory potentially causing a crash.

Asterisk Project Security Advisory - 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.

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.
