- ---------------------------------------------------------------------1. Summary:

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

3. Problem description:

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.

4. Solution:

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

This update is available via Red Hat Network.  To use Red Hat Network,
