Description

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

An integer overflow flaw, leading to a heap-based buffer overflow, was
found in the PostgreSQL handling code for regular expressions. A remote
attacker could use a specially crafted regular expression to cause
PostgreSQL to crash or possibly execute arbitrary code. (CVE-2016-0773)

Upstream acknowledges Tom Lane and Greg Stark as the original reporters.

This update upgrades PostgreSQL to version 9.4.6. Refer to the Release

since the previous version.

All PostgreSQL users are advised to upgrade to these updated packages,
which correct this issue. If the rh-postgresql94-postgresql service is
running, it will be automatically restarted after installing this update.
