Description:
MU Security Research Team has reported a vulnerability in Asterisk, which can be exploited by malicious people to cause a DoS (Denial of Service).

The vulnerability is caused due to a NULL-pointer dereference error when handling SIP request messages. This can be exploited to crash the service via a specially crafted SIP message with no URI and SIP version sent to default port 5060/UDP.

The vulnerability is reported in version 1.4.0 and 1.2.15. Prior versions may also be affected.
