Description

A security issue has been found in the libpq component of PostgreSQL <
9.6.3, where the PGREQUIRESSL 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.

Impact

A remote attacker in position of man-in-the-middle can intercept and
alter every communication between a vulnerable client and a server.
