openssl: OpenSSL: Denial of Service via unbounded memory growth in QUIC server

A flaw was found in OpenSSL. A remote attacker could exploit this by sending a large number of QUIC Initial packets to an OpenSSL QUIC server. This can cause the server to allocate and queue new incoming channels without limit, leading to unbounded memory growth. The excessive memory consumption...
