Descriptions

The snprintf implementation 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 does not properly handle system-call errors, which allows attackers to obtain sensitive information or have other unspecified impact via unknown vectors, as demonstrated by an out-of-memory error.

La implementación de snprintf 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, no maneja apropiadamente los errores de llamadas al sistema , lo que permite a atacantes obtener información confidencial o tener otro impacto no especificado por medio de vectores desconocidos, como es demostrado por un error fuera de la memoria.

It was discovered that PostgreSQL did not properly check the return values of certain standard library functions. If the system was in a state that would cause the standard library functions to fail (for example, memory exhaustion), an authenticated user could possibly exploit this flaw to disclose partial memory contents or cause the GSSAPI authentication to use an incorrect keytab file.
