Georgi,

The bug that caused the browser to crash in this way was fixed in IE 4.01
(which BTW is what's in Win98). People using 4.01 or 4.01 with SP1 cannot be
crashed in this way.

Thanks,

Subject: Object tag crashes Internet Explorer 4.0


The <OBJECT> tag seems to crash Internet Explorer 4.0 under Win95 (don't
know about other versions/OS).
The following:
<OBJECT CLASSID=____More than 250 characters here____></OBJECT>
opens a dialog box "IEXPLORE: ...illegal operation" and closes IE 4.0,
or a blue screen with "Fatal exception 0E" and you need to reboot.
I don't think this is exploitable(?), but it is a bad "feature".
