(RHSA-2016:2606) Moderate: postgresql security and bug fix update

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

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.
