Updated php packages fix security vulnerabilities

An integer overflow flaw in PHP’s unserialize() function was reported. If unserialize() were used on untrusted data, this issue could lead to a crash or potentially information disclosure (CVE-2014-3669). A heap corruption issue was reported in PHP’s exif_thumbnail() function. A specially-crafted JPEG image could cause the PHP interpreter to crash or, potentially, execute arbitrary code (CVE-2014-3670). If client-supplied input was passed to PHP’s cURL client as a URL to download, it could return local files from the server due to improper handling of null bytes (PHP#68089). PHP has been updated to version 5.4.34 for Mageia 3 and 5.5.18 for Mageia 4, which fix these issues and other bugs. Additionally, the suhosin PHP extension has been updated to version 0.9.36 and a bug in the php zip extension that could cause a crash on Mageia 4 has been fixed (mga#13820)
