Microsoft has released Security Advisory 977981.  It details vulnerabilities in Internet Explorer 6 and 7 on various operating systems.  The advisory does not provide any patches or new versions at this point, but does provide several recommendations for mitigation.

WOT stands for Web Of Trust, it is a community knowledge based system where information on websites are shared. After installing the add-on, the links from search engines are tagged with extra symbols showing whether the site's "reputation" level. Very simple to understand, red means potentially bad site and green means good site.

WOT is available for both Firefox and IE . If you choose to use it, remember to contribute back to the project back by helping to rate sites as you visit them.

With IE8 coming in the not so distant future, Microsoft describes what's new for developers in this Readiness page.

Google toolbar crashes IE 8 when the user goes to certain web sites. It crashed for me when I visited http://my.ebay.ca  and  http://www.google.com/ig

Way to reproduce:

• Install Google tool bar, in my case toolbar was installed when I upgraded.
• go to http://www.google.com/ig Google toolbar gives you a crashed warning and takes IE with it.

Severity can be high if you had already set http://www.google.com/ig as your home page because you are stuck in an endless loop that can only be fixed if you uninstall the toolbar. Note that the crash doesn't occur if you are in Emulate IE7 mode.
