Descriptions

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.

Desbordamiento de buffer en la función read_server_hello en lib/gnutls_handshake.c en GnuTLS anterior a 3.1.25, 3.2.x anterior a 3.2.15 y 3.3.x anterior a 3.3.4 permite a servidores remotos causar una denegación de servicio (consumo de memoria) o posiblemente ejecutar código arbitrario a través de una sesión id larga en un mensaje ServerHello.

A flaw was found in the way GnuTLS parsed session IDs from ServerHello messages of the TLS/SSL handshake. A malicious server could use this flaw to send an excessively long session ID value, which would trigger a buffer overflow in a connecting TLS/SSL client application using GnuTLS, causing the client application to crash or, possibly, execute arbitrary code.
