PHP .htaccess denial of service
| php-htaccess-dos (22844) |  Low Risk |
Description:
PHP is vulnerable to a denial of service. If safe_mode is enabled and a .htaccess file is in the web root directory containing a php_value session.save_path statement, a denial of service condition will occur caused by a vulnerability in the apache2handler SAPI and the sapi_apache2.c file.
