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. (CVE-2014-3670) Multiple buffer overflow flaws were found in the way PHP parsed DNS responses. A malicious DNS server or a man-in-the-middle attacker could use these flaws to crash or, possibly, execute arbitrary code with the privileges of a PHP application that uses the dns_get_record() function. (CVE-2014-4049, CVE-2014-3597) Multiple denial of service flaws were found in the File Information (fileinfo) extension. A remote attacker could use these flaws to cause a PHP application using fileinfo to consume an excessive amount of CPU and possibly crash. (CVE-2014-0237, CVE-2014-0238, CVE-2014-3538) Multiple boundary check flaws were found in the File Information (fileinfo) extension. A remote attacker could use these flaws to cause a PHP application using fileinfo to crash. (CVE-2014-0207, CVE-2014-3478, CVE-2014-3479, CVE-2014-3480, CVE-2014-3487, CVE-2014-3587, CVE-2014-3710) A type confusion issue was found in PHP's phpinfo() function. A malicious script author could possibly use this flaw to disclose certain portions of server memory. (CVE-2014-4721) A type confusion issue was found in the SPL ArrayObject and SPLObjectStorage classes' unserialize() method. A remote attacker able to submit specially crafted input to a PHP application, which would then unserialize this input using one of the aforementioned methods, could use this flaw to execute arbitrary code with the privileges of the user running that PHP application. (CVE-2014-3515) Two use-after-free flaws were found in the way PHP handled certain Standard PHP Library (SPL) Iterators and ArrayIterators. A malicious script author could possibly use either of these flaws to disclose certain portions of server memory. (CVE-2014-4670, CVE-2014-4698) 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) It was found that PHP's gd extension did not properly handle file names with a null character. A remote attacker could possibly use this flaw to make a PHP application access unexpected files and bypass intended file system access restrictions. (CVE-2014-5120) A NULL pointer dereference flaw was found in the gdImageCreateFromXpm() function of PHP's gd extension. A remote attacker could use this flaw to crash a PHP application using gd via a specially crafted X PixMap (XPM) file. (CVE-2014-2497) An out of bounds read flaw was found in the way the xmlrpc extension parsed dates in the ISO 8601 format. A specially crafted XML-RPC request or response could possibly cause a PHP application to crash. (CVE-2014-3668) The CVE-2014-0207, CVE-2014-0237, CVE-2014-0238, CVE-2014-3478, CVE-2014-3479, CVE-2014-3480, CVE-2014-3487, and CVE-2014-3710 issues were discovered by Francisco Alonso of Red Hat Product Security; the CVE-2014-3538 issue was discovered by Jan Kaluža of the Red Hat Web Stack Team; the CVE-2014-3597 issue was discovered by David Kutálek of Red Hat BaseOS QE. All php55-php users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the httpd24-httpd service must be restarted for the update to take effect.
