available for Red Hat Enterprise Linux 6.

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

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

A memory leak error was discovered in the crypt() function of the
pgCrypto extension. An authenticated attacker could possibly use this
flaw to disclose a limited amount of the server memory.
(CVE-2015-5288)

All PostgreSQL users are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue. If the
postgresql service is running, it will be automatically restarted
after installing this update."
