openssl: QUIC server may trigger double free when processing INITIAL packet

A flaw was found in OpenSSL. A malformed INITIAL packet with an invalid DCID destination connection ID can cause the QUIC server to double free the QRX object. This issue leads to memory corruption, causing the termination of the QUIC server process and resulting in a denial of service...

openssl: QUIC ACK-only packet retention can cause memory exhaustion

A flaw was found in OpenSSL. The QUIC protocol implementation retains metadata for ACK-only packets for the lifetime of a connection, leading to excessive memory consumption. This allows a peer to repeatedly send ack-eliciting packets while not acknowledging ACK-only responses to cause memory...
