1. Summary:

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

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 double-free bug was found in the deserialization code of PHP. PHP
applications use the unserialize function on untrusted user data, which
could allow a remote attacker to gain access to memory or potentially
execute arbitrary code.  The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2004-1019 to this issue.

Flaws were found in the pack and unpack PHP functions. These functions
do not normally pass user supplied data, so they would require a malicious
PHP script to be exploited. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CAN-2004-1018 to this issue.

A bug was discovered in the initialization of the OpenSSL library, such
that the curl extension could not be used to perform HTTP requests over SSL
unless the php-imap package was installed.

Users of PHP should upgrade to these updated packages, which contain fixes
for these issues.

4. Solution:

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