Red Hat Security Advisory 2014-1013-01 - PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server. PHP's fileinfo module provides functions used to identify a particular file according to the type of data contained by the file. A denial of service flaw was found in the File Information extension rules for detecting AWK files. A remote attacker could use this flaw to cause a PHP application using fileinfo to consume an excessive amount of CPU. Multiple denial of service flaws were found in the way the File Information extension parsed certain Composite Document Format files. A remote attacker could use either of these flaws to crash a PHP application using fileinfo via a specially crafted CDF file.
