Moderate: postgresql security update

Updated postgresql packages that fix two security issues are now available
for Red Hat Enterprise Linux 3 and 4.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

PostgreSQL is an advanced Object-Relational database management system
(DBMS).

A flaw was found in the way the PostgreSQL server handles certain
SQL-language functions. An authenticated user could execute a sequence of
commands which could crash the PostgreSQL server or possibly read from
arbitrary memory locations. A user would need to have permissions to drop
and add database tables to be able to exploit this issue (CVE-2007-0555).

A denial of service flaw was found affecting the PostgreSQL server running
on Red Hat Enterprise Linux 4 systems. An authenticated user could execute
an SQL command which could crash the PostgreSQL server. (CVE-2006-5540)

Users of PostgreSQL should upgrade to these updated packages containing
PostgreSQL version 7.4.16 or 7.3.18, which correct these issues.

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

This update is available via Red Hat Network. To use Red Hat Network,

RPMs being upgraded on your system.
