Red Hat Security Advisory: postgresql security update Security Advisory secalert@redhat.com Red Hat Security Response Team RHSA-2012:1264 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 2012-09-13T17:04:02Z Updated postgresql packages that fix one security issue are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link 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) Red Hat would like to thank the PostgreSQL project for reporting this issue. Upstream acknowledges Peter Eisentraut as the original reporter. All PostgreSQL users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. 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.
