Descriptions

contrib/pgcrypto in PostgreSQL before 9.0.20, 9.1.x before 9.1.16, 9.2.x before 9.2.11, 9.3.x before 9.3.7, and 9.4.x before 9.4.2 uses different error responses when an incorrect key is used, which makes it easier for attackers to obtain the key via a brute force attack.

contrib/pgcrypto en PostgreSQL versiones anteriores a 9.0.20, versiones 9.1.x anteriores a 9.1.16, versiones 9.2.x anteriores a 9.2.11, versiones 9.3.x anteriores a 9.3.7 y versiones 9.4.x anteriores a 9.4.2, utiliza diferentes respuestas de error cuando una clave incorrecta se usada, lo que facilita a atacantes obtener la clave por medio de un ataque de fuerza bruta.

It was discovered that the pgcrypto module could return different error messages when decrypting certain data with an incorrect key. This could potentially help an authenticated user to launch a possible cryptographic attack, although no suitable attack is currently known.
