* A permission escalation vulnerability in Asterisk Manager Interface. This
would potentially allow remote authenticated users the ability to execute
commands on the system shell with the privileges of the user running the
Asterisk application.
* A heap overflow vulnerability in the Skinny Channel driver. The keypad
button message event failed to check the length of a fixed length buffer
before appending a received digit to the end of that buffer. A remote
authenticated user could send sufficient keypad button message events that
the buffer would be overrun.
* A remote crash vulnerability in the SIP channel driver when processing UPDATE
requests. If a SIP UPDATE request was received indicating a connected line
update after a channel was terminated but before the final destruction of the
associated SIP dialog, Asterisk would attempt a connected line update on a
non-existing channel, causing a crash.
