Serious bug in Linux kernel 2.2.0 allows users to crash the systemJan 28, 1999, 00:23 (4 Talkback[s])
Dan Burcaw posted to the Linux-kernel mailing list:
There is a bug that works only on the 2.2.0 kernel that will allow root and non-root users to crash the machine (the system reboots).
To replicate this bug do following:
Take any core file, and as normal user or root run: ldd core
The machine will reboot, saying that it cannot get execution permissions for ./core
As far as I can tell, this problem only affects x86 machines running 2.2.0. I know that PPC is not affected.
Note: This problem does not occur in kernels before 2.2.0, and is apparently fixed in 2.2.0ac1.
Thanks to Gennady Gurov (firstname.lastname@example.org) for discovering this problem.

Linux has announced that this will be fixed in 2.2.1, due in a few days. -lt ed.
