CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
A memory exhaustion vulnerability exists in the HTTP server due to unbounded use of the Content-Length header. The server allocates memory directly based on the attacker supplied header value without enforcing an upper limit. A crafted HTTP request containing an extremely large Content-Length value can trigger excessive memory allocation and server termination, even without sending a request body.
