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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64
Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64
Red Hat Enterprise Linux HPC Node (v. 6) - x86_64

3. 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)

Red Hat would like to thank PostgreSQL upstream for reporting this issue.
Upstream acknowledges Tom Lane and Greg Stark as the original reporters.

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.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.
