Description

Updated PHP packages that fix an integer overflow flaw are now available for Red Hat Enterprise Linux 2.1.

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

PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Web server.

An integer overflow was discovered in the PHP memory handling routines. If a script can cause memory allocation based on untrusted user data, a remote attacker sending a carefully crafted request could execute arbitrary code as the 'apache' user. (CVE-2006-4812)

This issue did not affect the PHP packages distributed with Red Hat Enterprise Linux 3 or 4.

Users of PHP should upgrade to these updated packages which contain a backported patch that corrects this issue.
