Descriptions

ssl/t1_lib.c in OpenSSL 0.9.8h through 0.9.8q and 1.0.0 through 1.0.0c allows remote attackers to cause a denial of service (crash), and possibly obtain sensitive information in applications that use OpenSSL, via a malformed ClientHello handshake message that triggers an out-of-bounds memory access, aka "OCSP stapling vulnerability."

ssl/t1_lib.c en OpenSSL v0.9.8h hasta v0.9.8q y v1.0.0 hasta v1.0.0c permite a atacantes remotos causar una denegación de servicio (por caída de la aplicación) y posiblemente obtener información sensible en las aplicaciones que utilizan OpenSSL, a través de un formato incorrecto de mensaje ClientHello que desencadena un acceso a memoria fuera de rango, también conocida como "vulnerabilidad de grapado OCSP."
