 Overview : This host is running Qbik WinGate, which is prone to Denial of
 Service Vulnerability.

 Vulnerability Insight :
        The vulnerability is caused due to a boundary error in the processing 
        of IMAP commands. This can be exploited by issuing an IMAP LIST command
        with an overly long argument.

        Impact : Exploiting this issue will consume computer resources and deny 
        access to legitimate users or to potentially compromise a vulnerable
        system or may allow execution of arbitrary code. 

 Impact Level : Application

 Affected Software/OS :
        WinGate 6.2.2 and prior versions on Windows (All).

 Fix : No solution/patch is available as on 14th August, 2008. Information
 regarding this issue will update once the solution details are available.

 CVSS Score :
        CVSS Base Score     : 6.3 (AV:N/AC:M/Au:N/Au:SI/C:N/I:N/A:C)
        CVSS Temporal Score : 5.7
 Risk factor : Medium";
