Oracle Linux 4 / 5 : postgresql (ELSA-2009-1484)
Medium Nessus Plugin ID 67936
SynopsisThe remote Oracle Linux host is missing one or more security updates.
DescriptionFrom Red Hat Security Advisory 2009:1484 :
Updated postgresql packages that fix two security issues are now available for Red Hat Enterprise Linux 4 and 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).
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).
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 :
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.
SolutionUpdate the affected postgresql packages.
