1.164.1. RHSA-2009:1484: Moderate security update
Important
This update has already been released (prior to the GA of this release) as the security errata RHSA-2009:1484
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).
It was discovered that the upstream patch for CVE-2007-6600 included in the Red Hat Security Advisory RHSA-2008:0038 did not include protection against misuse of the RESET ROLE and RESET SESSION AUTHORIZATION commands. An authenticated user could use this flaw to install malicious code that would later execute with superuser privileges. (CVE-2009-3230)
A flaw was found in the way PostgreSQL handled encoding conversion. A remote, authenticated user could trigger an encoding conversion failure, possibly leading to a temporary denial of service. Note: To exploit this issue, a locale and client encoding for which specific messages fail to translate must be selected (the availability of these is determined by an administrator-defined locale setting). (CVE-2009-0922)
Note: For Red Hat Enterprise Linux 4, this update upgrades PostgreSQL to version 7.4.26. For Red Hat Enterprise Linux 5, this update upgrades PostgreSQL to version 8.1.18. Refer to the PostgreSQL Release Notes for a list of changes:
http://www.postgresql.org/docs/7.4/static/release.html http://www.postgresql.org/docs/8.1/static/release.html
All PostgreSQL users should upgrade to these updated packages, which resolve these issues. If the postgresql service is running, it will be automatically restarted after installing this update.
