New IE Security Hole - And It's a Big One!
Tuesday August 24th, 1999
Yet another hole has been found in Internet Explorer's ActiveX implementation. This one allows arbitrary code to be written to the user's hard-drive. The bug was found by Georgi Guninski, who has found many security bugs in IE and Communicator. To read more about it, click here to visit Georgi's page. If you click "Test it" beside the name of this bug ("Executing programs with IE 5.0") while using IE, the page you visit will write a small bit of sample code to your StartUp menu. You've been warned. Georgi calls this bug "the most significant of my discoveries and the most dangerous also".
Thanks to Zaw for the news.

The immediate patch is to unregister the offending object that is being exploited or to remove it's "safe for scripting" capability.
This will prevent any malicious code from calling it, though it might cause problems if it is used elsewhere (e.g. from the active desktop)
