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.

PostgreSQL is an advanced object-relational database management system. 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. A stack overflow flaw was discovered in the way the PostgreSQL core server processed certain JSON or JSONB input. An authenticated attacker could possibly use this flaw to crash the server backend by sending specially crafted JSON or JSONB input.
