Re: New URL spoofing bug in Microsoft Internet Explorer

Under IE 6.0.2900.2180, this does not occur as you describe.

If the mouse pointer is pointed to the edge around the link,
"http://www.microsoft.com"; is displayed, but when the pointer is
directly over the link, "http://www.google.com"; is correctly
displayed.

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.
