SVCrash responds to svwar and svcrack SIP messages with a message that causes old versions to crash. it sends a SIP message response to
svwar.py which triggers an unhandled exception. This may allow victims of SIP floods due to attackers using
svwar.py to mitigate the attack temporarily. The bug in
svwar.py was also fixed. Additionally, the behavior that allowed it to keep sending messages even when not responses are received was also changed.
