Updated PHP packages that fix several security issues 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.

2. Relevant releases/architectures:

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

3. Problem description:

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

A denial of service flaw was found in the way PHP processed a deeply nested
array. A remote attacker could cause the PHP interpreter to crash by
submitting an input variable with a deeply nested array. (CVE-2007-1285)

A flaw was found in the way PHP's unserialize() function processes data. If
a remote attacker is able to pass arbitrary data to PHP's unserialize()
function, it may be possible for them to execute arbitrary code as the
apache user. (CVE-2007-1286)

A double free flaw was found in PHP's session_decode() function. If a
remote attacker is able to pass arbitrary data to PHP's session_decode()
function, it may be possible for them to execute arbitrary code as the
apache user. (CVE-2007-1711)

Users of PHP should upgrade to these updated packages which contain
backported patches to correct these issues.
