php security update

CentOS Errata and Security Advisory CESA-2007:0153

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

A flaw was found in the way the mbstring extension set global variables. A
script which used the mb_parse_str() function to set global variables could
be forced to enable the register_globals configuration option, possibly
resulting in global variable injection. (CVE-2007-1583)

A heap based buffer overflow flaw was discovered in PHP’s gd extension. A
script that could be forced to process WBMP images from an untrusted source
could result in arbitrary code execution. (CVE-2007-1001)

A buffer over-read flaw was discovered in PHP’s gd extension. A script that
could be forced to write arbitrary string using a JIS font from an
untrusted source could cause the PHP interpreter to crash. (CVE-2007-0455)

A flaw was discovered in the way PHP’s mail() function processed header
data. If a script sent mail using a Subject header containing a string from
an untrusted source, a remote attacker could send bulk e-mail to unintended
recipients. (CVE-2007-1718)

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