CVE Name Pending

Description A remotely exploitable crash vulnerability exists in the
SIP channel driver if an ACK with SDP is received after the
channel has been terminated. The handling code incorrectly
assumes that the channel will always be present.

Resolution A check has now been added which only parses SDP and applies
it if an Asterisk channel is present.

Note that Walter Doekes, OSSO B.V., is responsible for
diagnosing and providing the fix for this issue.
