Sorry about that, I checked the "has security impact" checkbox and that
marked it as private by default. This is a very well known problem
though so keeping secret certainly does not make sense. I have manually
removed the "private" flag now.
The content of the bug report was as follows:
---------------------------------------------
Repro steps:
1. Install gutsy gibbon (or probably any ubuntu)
2. Start a gnome terminal
3. Run this command:
:(){ :|:& };:
4. Ubuntu starts to work furiously, after less than a second terminal
gets flooded with "low resources" message, and within a few seconds the
whole machine breaks down complete to the point where no a single pixel
is updated and the mouse cannot be moved at all. It's not possible to
escape to a ALT-Fn console terminal and CTRL-ALT-DEL does not work.
Okay, so this is not as bad as winnuke.exe because it's not remote but I
just did it on my shared hosting co and their server went down. And I
mean seriously, there should be a way for a user to abort stuff that
hogs resources this type of complete breakdown is NEVER acceptible. I
had to power of the machine and my file system got royally screwed (long
fsck etc).
Some of you might say this is like the oldest trick in the book, yada
yada yada...

Dear kernel hackers,
This is a message from below 0x7FFFFFFF. Please look at this bug (it's
not a new concept but still):
https://bugs.launchpad.net/ubuntu/+bug/163185
It seems to want people to register to view it. I guess Ubuntu should fix
launchpad then we can see the bug report
