The following packages have been upgraded to a newer upstream version:
postgresql (9.2.18).

Security Fix(es):

  * A flaw was found in the way PostgreSQL server handled certain SQL
statements containing CASE/WHEN commands. A remote, authenticated attacker
could use a specially crafted SQL statement to cause PostgreSQL to crash or
disclose a few bytes of server memory or possibly execute arbitrary code.
(CVE-2016-5423)

  * A flaw was found in the way PostgreSQL client programs handled database
and role names containing newlines, carriage returns, double quotes, or
backslashes. By crafting such an object name, roles with the CREATEDB or
CREATEROLE option could escalate their privileges to superuser when a
superuser next executes maintenance with a vulnerable client program.
(CVE-2016-5424)

Red Hat would like to thank the PostgreSQL project for reporting these
issues. Upstream acknowledges Heikki Linnakangas as the original reporter
of CVE-2016-5423  and Nathan Bossart as the original reporter of
CVE-2016-5424.
