GnuTLS < 3.1.25, 3.2.x < 3.2.15, 3.3.x < 3.3.4 - Remote Code Execution via ServerHello Session ID
Buffer overflow in the read_server_hello function in lib/gnutls_handshake.c in GnuTLS before 3.1.25, 3.2.x before 3.2.15, and 3.3.x before 3.3.4 allows remote servers to cause a denial of service (memory corruption) or possibly execute arbitrary code via a long session id in a ServerHello message.
