Type/Severity

Security Advisory: Moderate

Topic

An updated perl-DBD-Pg package that fixes two security issues is now
available for Red Hat Enterprise Linux 5 and 6.

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.

Description

Perl DBI is a database access Application Programming Interface (API) for
the Perl language. perl-DBD-Pg allows Perl applications to access
PostgreSQL database servers.

Two format string flaws were found in perl-DBD-Pg. A specially-crafted
database warning or error message from a server could cause an application
using perl-DBD-Pg to crash or, potentially, execute arbitrary code with the
privileges of the user running the application. (CVE-2012-1151)

All users of perl-DBD-Pg are advised to upgrade to this updated package,
which contains a backported patch to fix these issues. Applications using
perl-DBD-Pg must be restarted for the update to take effect.
