 Overview : This host is running Ultra Office Control, which is prone to 
 multiple vulnerabilities.

 Vulnerability Insight :

        Error exists when handling parameters received by the HttpUpload()
        and Save() methods in OfficeCtrl.ocx file.

        Impact : Successful exploitation will allow execution of arbitrary
        code, stack-based buffer overflow, can overwrite arbitrary files
        on the vulnerable system by tricking a user into visiting a
        malicious website.

 Impact Level : Application

 Affected Software/OS :
        Ultra Office Control 2.x and prior versions on Windows (All). 

 Fix : No solution/patch is available as on 01st September, 2008. Information
 regarding this issue will be update once the solution details are available.
 For updates refer, http://www.ultrashareware.com/Ultra-Office-Control.htm 

 Quick Fix: Set a kill bit for the CLSID's
 {00989888-BB72-4E31-A7C6-5F819C24D2F7}

 Refer to following link to set kill-bit,
