Description

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

A buffer overflow flaw was found in the Exif extension. A specially crafted
JPEG or TIFF file could cause a PHP application using the exif_thumbnail()
function to crash or, possibly, execute arbitrary code with the privileges
of the user running that PHP application. (CVE-2014-3670)

An integer overflow flaw was found in the way custom objects were
unserialized. Specially crafted input processed by the unserialize()
function could cause a PHP application to crash. (CVE-2014-3669)

All php users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. After installing the
updated packages, the httpd daemon must be restarted for the update to
take effect.
