CVE-2023-39321: Panic when processing post-handshake message on QUIC connections in crypto/tls
First published: Wed Sep 06 2023(Updated: )
Golang Go is vulnerable to a denial of service, caused by a flaw when processing partial post-handshake message in QUICConn.HandleData in the crypto/tls package. By sending a specially crafted post-handshake message for a QUIC connection, a remote attacker could exploit this vulnerability to cause a denial of service condition.
