Red Hat Security Advisory 2015-1218-01 - PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server. A flaw was found in the way PHP parsed multipart HTTP POST requests. A specially crafted request could cause PHP to use an excessive amount of CPU time. An uninitialized pointer use flaw was found in PHP's Exif extension. A specially crafted JPEG or TIFF file could cause a PHP application using the exif_read_data() function to crash or, possibly, execute arbitrary code with the privileges of the user running that PHP application.
