Description

A flaw was found in openssl. A remote attacker could trigger a NULL pointer dereference by sending an unknown or unsupported cipher ID during the client hello callback in applications using the QUIC (Quick UDP Internet Connections) protocol. This vulnerability, occurring when the SSL_CIPHER_find() function is called in this specific context, leads to an abnormal termination of the running process, causing a Denial of Service (DoS).
