Descriptions

crypt_blowfish before 1.1, as used in PHP before 5.3.7 on certain platforms, PostgreSQL before 8.4.9, and other products, does not properly handle 8-bit characters, which makes it easier for context-dependent attackers to determine a cleartext password by leveraging knowledge of a password hash.

crypt_blowfish en versiones anteriores a 1.1, como se utiliza en PHP en versiones anteriores a 5.3.7 en ciertas plataformas, PostgreSQL en versiones anteriores a 8.4.9 y otros productos, no maneja adecuadamente caracteres de 8-bit, lo que hace más fácil a atacantes dependientes de contexto determinar una contraseña en texto plano aprovechando el conocimiento del hash de una contraseña.
