Apache And Nginx PHP Websites Denial Of Service Vulnerability

A denial of service vulnerability exists in PHP running with Apache and NGINX systems (PHP-FPM and PHP-CGI). The attacker can flood a Linux web server's CPU and RAM using standard HTTP requests. The vulnerability effects Apache or NGINX web servers that handle dynamic PHP content using either PHP-CGI or PHP-FPM (which includes WordPress websites). In addition, web server configurations will continue to keep the server's resources in use far past the end of the attack.
