Summary
postgresql-9.3, postgresql-9.5, postgresql-9.6 vulnerabilities
Details

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. (CVE-2017-7546)

Jeff Janes discovered that PostgreSQL incorrectly handled the pgusermappings catalog view. A remote attacker without server privileges could possibly use this issue to obtain certain passwords. (CVE-2017-7547)

Chapman Flack discovered that PostgreSQL incorrectly handled lo_put() permissions. A remote attacker could possibly use this issue to change the data in a large object. (CVE-2017-7548)
