RHEL 5 : postgresql (RHSA-2012:0677)
Medium Nessus Plugin ID 59222
SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated postgresql packages that fix two security issues are now available for Red Hat Enterprise Linux 5.
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).
The pg_dump utility inserted object names literally into comments in the SQL script it produces. An unprivileged database user could create an object whose name includes a newline followed by a SQL command.
This SQL command might then be executed by a privileged user during later restore of the backup dump, allowing privilege escalation.
CREATE TRIGGER did not do a permissions check on the trigger function to be called. This could possibly allow an authenticated database user to call a privileged trigger function on data of their choosing.
All PostgreSQL users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. If the postgresql service is running, it will be automatically restarted after installing this update.
SolutionUpdate the affected packages.
