RHSA-2009:1484: postgresql security update



PostgreSQL is an advanced object-relational database management system(DBMS).It was discovered that the upstream patch for CVE-2007-6600 included in theRed Hat Security Advisory RHSA-2008:0038 did not include protection againstmisuse of the RESET ROLE and RESET SESSION AUTHORIZATION commands. Anauthenticated user could use this flaw to install malicious code that wouldlater execute with superuser privileges. (CVE-2009-3230)A flaw was found in the way PostgreSQL handled encoding conversion. Aremote, authenticated user could trigger an encoding conversion failure,possibly leading to a temporary denial of service. Note: To exploit thisissue, a locale and client encoding for which specific messages fail totranslate must be selected (the availability of these is determined by anadministrator-defined locale setting). (CVE-2009-0922)Note: For Red Hat Enterprise Linux 4, this update upgrades PostgreSQL toversion 7.4.26. For Red Hat Enterprise Linux 5, this update upgradesPostgreSQL to version 8.1.18. Refer to the PostgreSQL Release Notes for alist of changes:http://www.postgresql.org/docs/7.4/static/release.htmlhttp://www.postgresql.org/docs/8.1/static/release.htmlAll PostgreSQL users should upgrade to these updated packages, whichresolve these issues.
