Description

Joomla! contains a flaw that may allow a remote denial of service. The issue is triggered when a remote attacker provides malformed HTML tags to the 'mosmsg' variable in the poll system. Due to an error in the anti cross site scripting (XSS) code in includes/phpInputFilter/class.inputfilter.php, such a request will cause a denial of service and may result in loss of availability for the system.
