Re: Potential overflow in Internet Explorer

Now I've seen the segfault of IE on an WinNT 4.0 with
Internet Exploder 5.00.2919.6307.

And what about this apache Forbidden message? Does anyone knows what
that is about?

Best Regards,
Felipe

Hi,

I've tried with different lenghts of "a"s up to 1024 chars.
The IE did NOT crashed, but when I used 1024 chars, I got a Forbidden
message from an Apache  1.3.17  running on a Linux Slackware 7.1 with
Kernel 2.2.18, instead of a 404.
I'm sure the URL doesn't exist because I run the machine. :-)

btw, the workstation is a win2k english professional edition with IE
version 5.00.2920.0000, cipher 56-bit.

Hi all --


    While doing some testing on a web server, I discovered that Internet
Explorer crashes when the following URL is typed in the address bar:


        http://www.server.com/[a lot of 'A's]


Here is the resulting dump:

    I am using version 5.50.4522.1800 on Win98 SE with all critical
updates
installed.  I attempted to reproduce this crash on three other machines
without success.  Their version numbers where:

        5.00.2614.3500,
        5.50.4134.0100,
        5.50.4134.0600

    It seems as though this may be some sort of regression error,
bad mix of software, or both.  Can anyone else reproduce this?
