PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server.
It was discovered that the PHP XSL extension did not restrict the file writing capability of libxslt. A remote attacker could use this flaw to create or overwrite an arbitrary file that is writable by the user running PHP, if a PHP script processed untrusted eXtensible Style Sheet Language Transformations (XSLT) content. (CVE-2012-0057)
Note: This update disables file writing by default. A new PHP configuration directive, ‘xsl.security_prefs’, can be used to enable file writing in XSLT.
A flaw was found in the way PHP validated file names in file upload requests. A remote attacker could possibly use this flaw to bypass the sanitization of the uploaded file names, and cause a PHP script to store the uploaded file in an unexpected directory, by using a directory traversal attack. (CVE-2012-1172)
It was discovered that the fix for CVE-2012-1823, released via a previous update, did not properly filter all php-cgi command line arguments. A specially crafted request to a PHP script could cause the PHP interpreter to output usage information that triggers an Internal Server Error. (CVE-2012-2336)
A memory leak flaw was found in the PHP strtotime() function call. A remote attacker could possibly use this flaw to cause excessive memory consumption by triggering many strtotime() function calls.
(CVE-2012-0789)
It was found that PHP did not check the zend_strndup() function’s return value in certain cases. A remote attacker could possibly use this flaw to crash a PHP application. (CVE-2011-4153)
All php users should upgrade to these updated packages, which contain backported patches to resolve these issues. After installing the updated packages, the httpd daemon must be restarted for the update to take effect.
