Descriptions

The Debian php_crypt_revamped.patch patch for PHP 5.3.x, as used in the php5 package before 5.3.3-7+squeeze4 in Debian GNU/Linux squeeze, the php5 package before 5.3.2-1ubuntu4.17 in Ubuntu 10.04 LTS, and the php5 package before 5.3.5-1ubuntu7.10 in Ubuntu 11.04, does not properly handle an empty salt string, which might allow remote attackers to bypass authentication by leveraging an application that relies on the PHP crypt function to choose a salt for password hashing.

El parche de Debian php_crypt_revamped.patch para PHP v5.3.x, como el usado en el paquete php5 anterior a v5.3.3-7+squeeze4 en Debian GNU/Linux squeeze, el paquete php5 anterior a v5.3.2-1ubuntu4.17 en Ubuntu 10.04 LTS, y el paquete php5 anterior a v5.3.5-1ubuntu7.10 en Ubuntu 11.04, no gestiona de forma adecuada una cadena de salto vacía, lo que podría permitir a atacantes remotos evitar la autenticación mediante el aprovechamiento de una aplicación que se basa en la función crypt de PHP para elegir el salto en el proceso de obtención del hash de una contraseña.
