Description

From Red Hat Security Advisory 2017:2860 :

An update for postgresql is now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

PostgreSQL is an advanced object-relational database management system (DBMS).

Security Fix(es) :

* 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. (CVE-2017-7546)

Red Hat would like to thank the PostgreSQL project for reporting this issue. Upstream acknowledges Ben de Graaff, Jelte Fennema, and Jeroen van der Ham as the original reporters.
