Descriptions

The crypt_des (aka DES-based crypt) function in FreeBSD before 9.0-RELEASE-p2, as used in PHP, PostgreSQL, and other products, does not process the complete cleartext password if this password contains a 0x80 character, which makes it easier for context-dependent attackers to obtain access via an authentication attempt with an initial substring of the intended password, as demonstrated by a Unicode password.

La función crypt_des (también conocido como crypt basado en DES), en FreeBSD v9.0-RELEASE-p2, tal y como se utiliza en PHP, PostgreSQL y otros productos, no procesa las contraseñas en claro si la contraseña contiene un carácter de 0x80, lo que hace más fácil para los atacantes dependientes del contexto a la hora de obtener acceso a través de un intento de autenticación con una subcadena inicial con la contraseña, tal y como se demuestra con una contraseña Unicode.
