(RHSA-2007:0355) Important: php security update

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.
(CVE-2007-2509)

A buffer overflow flaw was found in the PHP ‘soap’ extension, regarding the
handling of an HTTP redirect response when using the SOAP client provided
by this extension with an untrusted SOAP server. No mechanism to trigger
this flaw remotely is known. (CVE-2007-2510)

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