CVE-2017-7546 [CRITICAL] PostgreSQL vulnerabilities
Title: PostgreSQL vulnerabilities
Summary: Several security issues were fixed in PostgreSQL.
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. (C

postgresql: lo_put() function ignores ACLs
PostgreSQL versions before 9.4.13, 9.5.8 and 9.6.4 are vulnerable to authorization flaw allowing remote authenticated attackers with no privileges on a large object to overwrite the entire contents of the object, resulting in a denial of service.
An authorization flaw was found in the way PostgreSQL handled large objects. A remote, authenticated attacker with no privileges on a large object could potentially use this flaw to overwrite the entire content of the object, thus resulting in denial of service.
