Interpretation conflict in PHP Toolkit before 1.0.1 on Gentoo Linux might allow local users to cause a denial of service (PHP outage) and read contents of PHP scripts by creating a file with a one-letter lowercase alphabetic name, which triggers interpretation of a certain unquoted [a-z] argument as a matching shell glob for this name, rather than interpretation as the literal [a-z] regular-expression string, and consequently blocks the launch of the PHP interpreter within the Apache HTTP Server.Show less

plugins/maps/db_handler.php in LinPHA 1.3.3 and earlier does not require authentication for a settings action that modifies the configuration file, which allows remote attackers to conduct directory traversal attacks and execute arbitrary local files by placing directory traversal sequences into the maps_type configuration setting, and then sending a request to maps_view.php, which causes plugins/maps/map.main.class.php to use the modified configuration.Show less
