Asterisk SIP Channel Driver Response Code Zero Remote Denial of Service Vulnerability

Asterisk SIP Channel Driver Response Code Zero Remote Denial of Service Vulnerability

Asterisk is prone to a remote denial-of-service vulnerability because the application fails to properly handle certain SIP packets.

Exploiting this issue allows remote attackers to cause the application to crash, effectively denying service to legitimate users.

Asterisk versions prior to 1.2.18 and 1.4.3 are vulnerable to this issue.
