Red Hat Security Advisory: postgresql and postgresql84 security update Security Advisory secalert@redhat.com Red Hat Security Response Team RHSA-2012:1263 Final 1 1 2012-09-13T16:46:00Z Current version 2012-09-13T16:46:00Z 2012-09-13T16:46:00Z Red Hat rhsa-to-cvrf 1.0.1484 2012-09-13T17:16:02Z Updated postgresql84 and postgresql packages that fix two security issues are now available for Red Hat Enterprise Linux 5 and 6 respectively. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. PostgreSQL is an advanced object-relational database management system (DBMS). It was found that the optional PostgreSQL xml2 contrib module allowed local files and remote URLs to be read and written to with the privileges of the database server when parsing Extensible Stylesheet Language Transformations (XSLT). An unprivileged database user could use this flaw to read and write to local files (such as the database's configuration files) and remote URLs they would otherwise not have access to by issuing a specially-crafted SQL query. (CVE-2012-3488) It was found that the "xml" data type allowed local files and remote URLs to be read with the privileges of the database server to resolve DTD and entity references in the provided XML. An unprivileged database user could use this flaw to read local files they would otherwise not have access to by issuing a specially-crafted SQL query. Note that the full contents of the files were not returned, but portions could be displayed to the user via error messages. (CVE-2012-3489) Red Hat would like to thank the PostgreSQL project for reporting these issues. Upstream acknowledges Peter Eisentraut as the original reporter of CVE-2012-3488, and Noah Misch as the original reporter of CVE-2012-3489. These updated packages upgrade PostgreSQL to version 8.4.13. Refer to the PostgreSQL Release Notes for a list of changes: http://www.postgresql.org/docs/8.4/static/release-8-4-13.html All PostgreSQL users are advised to upgrade to these updated packages, which correct these issues. If the postgresql service is running, it will be automatically restarted after installing this update. Please see https://www.redhat.com/footer/terms-of-use.html Copyright © 2012 Red Hat, Inc.
