Synopsis

Moderate: perl-DBD-Pg security update

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.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

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.

A heap-based buffer overflow flaw was discovered in the pg_getline function
implementation. If the pg_getline or getline functions read large,
untrusted records from a database, it could cause an application using
these functions to crash or, possibly, execute arbitrary code.
(CVE-2009-0663)

Note: After installing this update, pg_getline may return more data than
specified by its second argument, as this argument will be ignored. This is
consistent with current upstream behavior. Previously, the length limit
(the second argument) was not enforced, allowing a buffer overflow.

A memory leak flaw was found in the function performing the de-quoting of
BYTEA type values acquired from a database. An attacker able to cause an
application using perl-DBD-Pg to perform a large number of SQL queries
returning BYTEA records, could cause the application to use excessive
amounts of memory or, possibly, crash. (CVE-2009-1341)

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

Solution

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
