TinyWeb 0.0.8 Null Pointer Dereference DoS via Malformed HTTP Request

Published Jul 28, 2026 · Updated Jul 28, 2026 · Assigned by VulnCheck

Vendor: GeneralSandman Product: TinyWeb

Description

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.
