Title: Microsoft Internet Explorer Modeless Dialog DoS Vulnerability
Severity: MODERATE
Description:
A modeless dialog method is a dialog box which continues to display even when a user switches to other applications.
An issue has been reported in Microsoft Internet Explorer, which could enable a malicious web host to cause a visiting user's system to consume all available system resources.
This is achieved when including the showModelessDialog() function within a HTML document. If the value passed to this function is the file the function is included in, an endless loop will be initiated.
This has reportedly causes 100% CPU usage even after the iexplore.exe process has been ended. A reboot may be required in order to gain normal functionality.
