Summary
Red Hat Security Advisory: perl-DBD-Pg security update

Notes

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.
Details
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.
