PHP Exposure of Sensitive Information to an Unauthorized Actor Vulnerability - CVE-2014-4721
The phpinfo implementation in ext/standard/info.c in PHP before 5.4.30 and 5.5.x before 5.5.14 does not ensure use of the string data type for the PHP_AUTH_PW PHP_AUTH_TYPE PHP_AUTH_USER and PHP_SELF variables which might allow context-dependent attackers to obtain sensitive information from process memory by using the integer data type with crafted values related to a quottype confusionquot vulnerability as demonstrated by reading a private SSL key in an Apache HTTP Server web-hosting environment with mod_ssl and a PHP 5.3.x mod_php.
