Threat database

HTTP::Server::PSGI versions before 1.0056 for Perl contain a vulnerability where a remote attacker can crash the server by sending a request with a large Content-Length header. The server attempts to allocate memory based on the declared Content-Length before reading the body, leading to an out-of-memory error and server crash. Since HTTP::Server::PSGI runs as a single process, the server remains down until manually restarted.
