1. Summary:

Updated PHP packages that fix multiple security issues are now available
for Red Hat Enterprise Linux 2.1.

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

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64
Red Hat Linux Advanced Workstation 2.1 - ia64
Red Hat Enterprise Linux ES version 2.1 - i386
Red Hat Enterprise Linux WS version 2.1 - i386

3. Problem description:

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

A response-splitting issue was discovered in the PHP session handling. If
a remote attacker can force a carefully crafted session identifier to be
used, a cross-site-scripting or response-splitting attack could be
possible. (CVE-2006-3016)

A buffer overflow was discovered found in the PHP sscanf() function. If a
script used the sscanf() function with positional arguments in the format
string, a remote attacker sending a carefully crafted request could execute
arbitrary code as the 'apache' user. (CVE-2006-4020)

An integer overflow was discovered in the PHP wordwrap() and str_repeat()
functions. If a script running on a 64-bit server used either of these
functions on untrusted user data, a remote attacker sending a carefully
crafted request might be able to cause a heap overflow. (CVE-2006-4482)

An integer overflow was discovered in the PHP memory allocation handling.
On 64-bit platforms, the "memory_limit" setting was not enforced correctly,
which could allow a denial of service attack by a remote user. (CVE-2006-4486)

Users of PHP should upgrade to these updated packages which contain
backported patches to correct these issues. These packages also contain a
fix for a bug where certain input strings to the metaphone() function could
cause memory corruption.

4. Solution:

Before applying this update, make sure all previously released errata
