Descriptions
In PostgreSQL 9.3.x before 9.3.17, 9.4.x before 9.4.12, 9.5.x before 9.5.7, and 9.6.x before 9.6.3, it was found that the PGREQUIRESSL environment variable was no longer enforcing a SSL/TLS connection to a PostgreSQL server. An active Man-in-the-Middle attacker could use this flaw to strip the SSL/TLS protection from a connection between a client and a server.
En PostgreSQL, en versiones 9.3.x anteriores a la 9.3.17, versiones 9.4.x anteriores a la 9.4.12, versiones 9.5.x anteriores a la 9.5.7, y versiones 9.6.x anteriores a la 9.6.3, se ha descubierto que la variable de entorno PGREQUIRESSL ya no requería una conexión SSL/TLS a un servidor PostgreSQL. Un atacante Man-in-the-Middle (MitM) activo podría utilizar este fallo para eliminar la protección SSL/TLS de una conexión entre un cliente y un servidor.
It was discovered that the PostgreSQL client library (libpq) did not enforce the use of TLS/SSL for a connection to a PostgreSQL server when the PGREQUIRESSL environment variable was set. An man-in-the-middle attacker could use this flaw to strip the SSL/TLS protection from a connection between a client and a server.
