Several vulnerabilities were found in PHP, a general-purpose scripting language commonly used for web application development. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2014-3538 It was discovered that the original fix for CVE-2013-7345 did not sufficiently address the problem. A remote attacker could still cause a denial of service via a specially-crafted input file that triggers backtracking during processing of an awk regular expression rule. CVE-2014-3587 It was discovered that the CDF parser of the fileinfo module does not properly process malformed files in the Composite Document File format, leading to crashes. CVE-2014-3597 It was discovered that the original fix for CVE-2014-4049 did not completely address the issue. A malicious server or man-in-the-middle attacker could cause a denial of service and possibly execute arbitrary code via a crafted DNS TXT record. CVE-2014-4670 It was discovered that PHP incorrectly handled certain SPL Iterators. A local attacker could use this flaw to cause PHP to crash, resulting in a denial of service.
