| Description: | 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 buffer overflow flaw was found in the way the File Information (fileinfo)extension processed certain Pascal strings. A remote attacker able to makea PHP application using fileinfo convert a specially crafted Pascal stringprovided by an image file could cause that application to crash.(CVE-2014-3478)Multiple flaws were found in the File Information (fileinfo) extensionregular expression rules for detecting various files. A remote attackercould use either of these flaws to cause a PHP application using fileinfoto consume an excessive amount of CPU. (CVE-2014-3538)It was found that the fix for CVE-2012-1571 was incomplete; the FileInformation (fileinfo) extension did not correctly parse certain CompositeDocument Format (CDF) files. A remote attacker could use this flaw to crasha PHP application using fileinfo via a specially crafted CDF file.(CVE-2014-3587)It was found that PHP's gd extension did not properly handle file nameswith a null character. A remote attacker could possibly use this flaw tomake a PHP application access unexpected files and bypass intended filesystem access restrictions. (CVE-2014-5120)A NULL pointer dereference flaw was found in the gdImageCreateFromXpm()function of PHP's gd extension. A remote attacker could use this flaw tocrash a PHP application using gd via a specially crafted X PixMap (XPM)file. (CVE-2014-2497)Multiple buffer over-read flaws were found in the php_parserr() function ofPHP. A malicious DNS server or a man-in-the-middle attacker could possiblyuse this flaw to execute arbitrary code as the PHP interpreter if a PHPapplication used the dns_get_record() function to perform a DNS query.(CVE-2014-3597)Two use-after-free flaws were found in the way PHP handled certain StandardPHP Library (SPL) Iterators and ArrayIterators. A malicious script authorcould possibly use either of these flaws to disclose certain portions ofserver memory. (CVE-2014-4670, CVE-2014-4698)The CVE-2014-3478 issue was discovered by Francisco Alonso of Red HatProduct Security, the CVE-2014-3538 issue was discovered by Jan KaluЕѕa ofthe Red Hat Web Stack Team, and the CVE-2014-3597 issue was discovered byDavid KutГЎlek of the Red Hat BaseOS QE.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. |
