Descriptions

The crypt function in contrib/pgcrypto in PostgreSQL before 9.0.23, 9.1.x before 9.1.19, 9.2.x before 9.2.14, 9.3.x before 9.3.10, and 9.4.x before 9.4.5 allows attackers to cause a denial of service (server crash) or read arbitrary server memory via a "too-short" salt.

La función crypt en contrib/pgcrypto en PostgreSQL en versiones anteriores a 9.0.23, 9.1.x en versiones anteriores a 9.1.19, 9.2.x en versiones anteriores a 9.2.14, 9.3.x en versiones anteriores a 9.3.10 y 9.4.x en versiones anteriores a 9.4.5 permite a atacantes provocar una denegación de servicio (caída del servidor) o leer la memoria del servidor arbitrariamente a través de un salt 'too-short'.

A memory leak error was discovered in the crypt() function of the pgCrypto extension. An authenticated attacker could possibly use this flaw to disclose a limited amount of the server memory.
