Russ from NTBugTraq helped to clear some of this up. If you hover the
mouse below the actual link to Google - in a very narrow area - the
status bar will show www.microsoft.com, but clicking doesn't do
anything. So it's definitely a stupid error in IE, but the spoofing
angle in SP2 is debatable.

Same version I tested, Larry. (Same results too, for the most part.) Try
looking at my page for another example (as I stated in my previous
emails), as well as a way it might "work" in a sense:

FYI: It seems my emails from 10/28 may have not made it to the list yet
(?). They are included.

Has no problem - the status bar says Google and the click goes to 
Google

New URL spoofing bug in Microsoft Internet Explorer

There is a security bug in Internet Explorer 6.0.2800.1106 (fully 
patched), which allowes to show any faked target-address in the status

bar of the window.

The example below will display a faked URL 
("http://www.microsoft.com/";) in the status bar of the window, if you
move your mouse over the link.
Click on the link and IE will go to "http://www.google.com/"; and NOT 
to "http://www.microsoft.com/"; .

<a href="http://www.microsoft.com/";><table><tr><td><a
href="http://www.google.com/";>Click here</td></tr></table></a>

Description: Microsoft Internet Explorer can't handle links surrounded

by a table and an other link correct.

The bug can be exploited using HTML mail message too.

Affected software: Microsoft Internet Explorer, Microsoft Outlook 
Express, ...

Workaround: Don't click on non-trusted links. Or right-click on links 
to see the real target. Or use Copy-and-Paste.
