This signature detects attempts to exploit a known vulnerability against CUPS. A successful attack can result in a denial-of-service condition.
CUPS is prone to a denial-of-service vulnerability because of a NULL-pointer dereference that occurs when processing two consecutive IPP_TAG_UNSUPPORTED tags in specially crafted IPP (Internet Printing Protocal) packets. An attacker can exploit this issue to crash the affected application, denying service to legitimate users.
