Red Hat Security Advisory 2017-2678-01 - PostgreSQL is an advanced object-relational database management system. The following packages have been upgraded to a later upstream version: rh-postgresql94-postgresql. Security Fix: It was found that authenticating to a PostgreSQL database account with an empty password was possible despite libpq's refusal to send an empty password. A remote attacker could potentially use this flaw to gain access to database accounts with empty passwords.

Ubuntu Security Notice 3390-1 - Ben de Graaff, Jelte Fennema, and Jeroen van der Ham discovered that PostgreSQL allowed the use of empty passwords in some authentication methods, contrary to expected behaviour. A remote attacker could use an empty password to authenticate to servers that were believed to have password login disabled. Jeff Janes discovered that PostgreSQL incorrectly handled the pg_user_mappings catalog view. A remote attacker without server privileges could possibly use this issue to obtain certain passwords. Various other issues were also addressed.
