Descriptions

Large handshake records may cause panics in crypto/tls. Both clients and servers may send large TLS handshake records which cause servers and clients, respectively, to panic when attempting to construct responses. This affects all TLS 1.3 clients, TLS 1.2 clients which explicitly enable session resumption (by setting Config.ClientSessionCache to a non-nil value), and TLS 1.3 servers which request client certificates (by setting Config.ClientAuth >= RequestClientCert).

A flaw was found in Golang Go, where it is vulnerable to a denial of service caused when processing large TLS handshake records. By sending specially-crafted TLS handshake records, a remote, authenticated attacker can cause a denial of service condition.
