Red Hat Security Advisory 2014-1765-01 – 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. 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.
