Description

A flaw was found in cpp-httplib. A remote attacker, acting as a malicious server or through a man-in-the-middle position, can send a specially crafted HTTP response with a malformed Content-Length header. This lack of input validation and exception handling causes the client application to crash, resulting in a Denial of Service (DoS).
