The image does not need to be that large, a very small one is sufficient
Just the /declaration/ of the size is enough to trigger the bug

Save your data before. The machine will BSOD

It didn't crash the box I'm on right now... XP Pro SP2, fully patched.
Just put it together yesterday, since my little AMD1500+ finally bit the
dust :(

XP SP2 here and nothing happened with either Firefox or IE, just a
broken graphic image with very large vertical and horizontal scroll.

Your error message says that "the display driver for RADEON IGP 320M
seems to be responsible for the system instability."

I have a different graphics card/driver (Nvidia) which doesn't have
this problem.

I'll recant my original post that this can't happen since this appears
to be a driver issue.

Tried it. No BSOD. No crash. IE simply doesn't display the image with a
width and height of 9999999. Dropping a digit (999999) shows the image
but it's very slow. Dropping another digit (99999) shows the image and
scrolling is sluggish but usable.

Nice FUD though. BSOD... now that would be a lie.

How is it a "lie" when it has been confirmed by other people? Perhaps it
depends on the amount of total memory you have on your system as to
whether it actually crashes or not.

The point here is that a friggin WEB BROWSER has the capability of
potentially crashing a Windows system simply because the platform will
allocate all available memory to trying to display this massive graphic,
even to the point of taking away memory from its core components.

And yet you wintards have the audacity to call this platform stable and
secure. What a fsckin joke! Now, for an ancore performance, let's see
how long it takes for M$ to get up off it's ass and fix this little bug.

Needless to say, with Linux and OSS it would have been probably been fixed
yesterday.

My machine uses the /very/ standard Intel i815 onboard graphics chip and
it rebooted.

The odds that everyone who has had this problem is using the same video driver
are probably pretty long. Did you test with multiple src's as suggested
in the PDF that Peter linked?

It's a video driver error - it has nothing to do with memory. It works on
my little 64MB nVidia card that's in this box. Sure, it slows things
down, but it doesn't crash. The problem is crappy video drivers - which,
as we all know and have discussed, run in kernel space. So, if the driver
craps out, so does the system. It appears that nVidia drivers (at least
the latest) don't have this problem.

I don't think MS is the one to fix this. The one to fix this is the
driver vendors where this is an issue.

I suppose as far as MS is involved, you have the video driver in ring0
issue, which isn't going to change. It's interesting, but the very few
BSOD's I've had since 2K and XP - have almost always been video driver
related. What, I think is that ms should give an option to either run
the driver in kernel space - if you need gui performance, or run in user
space if you are on a server or other machine where your not doing
anything intensive... Just a thought.

It's a driver issue. No different than the recent bug where sometimes
running 'tar' to archive a file causes a kernel panic in linux. Last I
checked 'tar' was even more rudimentary than a web browser so why is
tar bringing down a Linux system?

A little knowledge can be a dangerous thing.

To reboot open up a console window and type:

shutdown -r

Broken graphic image? You mean it didn't really point to an image file?
If not, try it.

Not sure if it works or not... But, I have been able to do it through
the menu on the task manager in the past :)


Wow...thanks.

I didn't even know that was there ( I remember it having to be something
that was installed with the NT Resource Kit ! ).

Tom,

C'mon.

You windows guys have been rolling out this argument forever.

First you claim Linux doesn't have hardware support as an argument
against Linux.

Then everytime an exploit is pointed out you claim that it's "3rd party
software" that "isn't written right".

Bottom line: if an OS can't deal with incorrectly written application
software or drivers -- then it's not very good.

Wow... my machine came to a crawl...

Then I hit alt-f4 a few times and it was gone. whew.

Didn't BSOD, and it recovered quickly after I killed IE.

And to say Windows can't handle large images, well...
9999999x9999999x32 (argb) pixels is about 3199999360 *gigabytes* of
memory.

I doubt many machines handle images that large :)

I pointed it to an image file the second time. Interestingly, task
manager didn't show memory being eaten up but I could hear the hard
drive grinding. I was able to shut IE down so I'd say that a memory
leak has been found. I don't know that I'd worry about the ability for
DOS more than I'd worry about a possible exploit to gain control of the
machine. To be honest, worst experience I ever had was with
openoffice.org that I got via yum on FC3. Right clicking to spell check
resulted in 45 minutes of thrashing, then the killing of processes when
swap ran out, then a kernel panic(only one I've ever had under Linux).
