Descriptions

The SSL 3.0 implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f does not properly initialize data structures for block cipher padding, which might allow remote attackers to obtain sensitive information by decrypting the padding data sent by an SSL peer.

La implementación SSL v3.0 en OpenSSL antes de v0.9.8s y v1.x antes de v1.0.0f no inicializa correctamente las estructuras de datos para el relleno de bloques de cifrado, lo que podría permitir a atacantes remotos obtener información sensible descifrando los datos de rellenos enviados por uno de los extremos de la comunicación SSL.
