Updated PHP packages that fix two security issues are now available for Red
Hat Enterprise Linux 4.
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 heap buffer overflow flaw was found in the PHP 'xmlrpc' extension. A
PHP script which implements an XML-RPC server using this extension could
allow a remote attacker to execute arbitrary code as the 'apache' user.
Note that this flaw does not affect PHP applications using the pure-PHP
XML_RPC class provided in /usr/share/pear. (CVE-2007-1864)
A flaw was found in the PHP 'ftp' extension. If a PHP script used this
extension to provide access to a private FTP server, and passed untrusted
script input directly to any function provided by this extension, a remote
attacker would be able to send arbitrary FTP commands to the server.
Users of PHP should upgrade to these updated packages which contain
backported patches to correct these issues.
