Descriptions

The Server Gated Cryptography (SGC) implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f does not properly handle handshake restarts, which allows remote attackers to cause a denial of service (CPU consumption) via unspecified vectors.

La implementación del servidor de criptografía SGC en OpenSSL antes de v0.9.8s y en v1.x antes de v1.0.0f no controla correctamente los reinicios de 'handshake' (apretón de manos), lo que permite a atacantes remotos provocar una denegación de servicio a través de vectores no especificados.
