Short explanation
HTTP::Server::PSGI for Perl before versions 1.0056 allows a single request to crash the server by declaring a large Content-Length.
A remote attacker can cause the server to exhaust memory and remain down until restarted by sending a single malicious request.
What should be done?
- Follow vendor advisories and patch recommendations
- Update the HTTP::Server::PSGI installation
Chain of evidence and sources

Sunucu tek bir işlem olarak çalıştığı için yeniden başlatılana kadar kapalı kalır.
Show the technical text from the sources
HTTP::Server::PSGI versions before 1.0056 for Perl allow a single request to crash the server by declaring a large Content-Length. The request body is read with sysread() calls sized by the remaining Content-Length. Perl grows the read buffer to the requested length before any data arrives, so the server tries to allocate as much memory as the client declares. A remote attacker can send one request with a large Content-Length and a few body bytes, and perl exits with an out-of-memory error before the application is called. HTTP::Server::PSGI runs as a single process, so the server stays down until restarted.
