"Updated PHP packages that fix a security issue are now available.

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.

A bug was discovered in the PEAR XML-RPC Server package included in
PHP. If a PHP script is used which implements an XML-RPC Server using
the PEAR XML-RPC package, then it is possible for a remote attacker to
construct an XML-RPC request which can cause PHP to execute arbitrary
PHP commands as the 'apache' user. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CVE-2005-2498
to this issue.

When using the default SELinux 'targeted' policy on Red Hat Enterprise
Linux 4, the impact of this issue is reduced since the scripts
executed by PHP are constrained within the httpd_sys_script_t security
context.

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