SSL: Server Hello Session ID Overflow
This signature detects overlarge Session ID's in a Server Hello message. A successful attack could result in arbitrary code execution with the privileges of the receiving client process, possibly root.
Extended Description
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.
