What it is

Reported

TinyWeb through 0.0.8 contains a null pointer dereference vulnerability that allows unauthenticated remote attackers to crash worker processes by sending a malformed HTTP request line with an invalid version string. The HttpParser::execute() function fails to allocate the Url object when version parsing fails, leaving the url pointer NULL, and buildResponse() subsequently dereferences this NULL pointer without checking the valid_requ flag, producing a SIGSEGV that terminates the worker process and, when repeated across all workers, takes the server permanently offline until manually restarted. Source description excerpt; complete tracked detail loads below.
