PHP is an HTML-embedded scripting language commonly used with the ApacheHTTP Server. PHP's fileinfo module provides functions used to identify aparticular file according to the type of data contained by the file.A denial of service flaw was found in the File Information (fileinfo)extension rules for detecting AWK files. A remote attacker could use thisflaw to cause a PHP application using fileinfo to consume an excessiveamount of CPU. (CVE-2013-7345)Multiple denial of service flaws were found in the way the File Information(fileinfo) extension parsed certain Composite Document Format (CDF) files.A remote attacker could use either of these flaws to crash a PHPapplication using fileinfo via a specially crafted CDF file.(CVE-2014-0207, CVE-2014-0237, CVE-2014-0238, CVE-2014-3479, CVE-2014-3480,CVE-2014-3487)A heap-based buffer overflow flaw was found in the way PHP parsed DNS TXTrecords. A malicious DNS server or a man-in-the-middle attacker couldpossibly use this flaw to execute arbitrary code as the PHP interpreter ifa PHP application used the dns_get_record() function to perform a DNSquery. (CVE-2014-4049)A type confusion issue was found in PHP's phpinfo() function. A maliciousscript author could possibly use this flaw to disclose certain portions ofserver memory. (CVE-2014-4721)A type confusion issue was found in the SPL ArrayObject andSPLObjectStorage classes' unserialize() method. A remote attacker able tosubmit specially crafted input to a PHP application, which would thenunserialize this input using one of the aforementioned methods, could usethis flaw to execute arbitrary code with the privileges of the user runningthat PHP application. (CVE-2014-3515)The CVE-2014-0207, CVE-2014-0237, CVE-2014-0238, CVE-2014-3479,CVE-2014-3480, and CVE-2014-3487 issues were discovered by Francisco Alonsoof Red Hat Product Security.All php users are advised to upgrade to these updated packages, whichcontain backported patches to correct these issues. After installing theupdated packages, the httpd daemon must be restarted for the update totake effect.
