"Updated postgresql packages that fix several security issues are now
available for Red Hat Enterprise Linux 5.

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).

Two flaws were 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 these issues
(CVE-2007-0555, CVE-2007-0556).

Several denial of service flaws were found in the PostgreSQL server.
An authenticated user could execute certain SQL commands which could
crash the PostgreSQL server (CVE-2006-5540, CVE-2006-5541,
CVE-2006-5542).

Users of PostgreSQL should upgrade to these updated packages
containing PostgreSQL version 8.1.8 which corrects these issues."
