CVE-2017-7546

Affected: postgresql

PostgreSQL versions before 9.2.22, 9.3.18, 9.4.13, 9.5.8 and 9.6.4 are vulnerable to incorrect authentication flaw allowing remote attackers to gain access to database accounts with an empty password.

USN-3390-1 — postgresql-9.3, postgresql-9.5, postgresql-9.6 vulnerabilities

Affected: Ubuntu:14.04:LTS: postgresql-9.3, Ubuntu:16.04:LTS: postgresql-9.5

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 pg_user_mappings 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)
