S, RE: Pentium F0 bug. Look at USENET POSTS xp9.dejanews.com and search for F0 or F0 bug Many users are reconsidering their impending purchase of Pentium PRO and Pentium II servers because of the growing FUD, but in reality, how do we know that there isn't a similar bug in P6 generation? You of course know for sure that there is no workaround right? What workaround do you expect, S? Microcode cannot be patched, its in the silicon. If this were not true, would Intel have waited 3 years to fix dozens of bugs documented in the spec revision? Software scanning for the code is useless because any hacker could write code in their sleep which generates the 0FF0C7C8 one microsecond before executing it. Petz

An unbiased view of the Intel F0 bug from "Wired": wired.com "If someone just has FTP access to an account and they can put programs up and execute them as CGI programs on a Web server, you can put this program up," said Stefan Hudson, senior network administrator at Monterey Bay Internet. "All it needs to do is run and it takes down the whole machine." "Many ISPs use Pentium servers running Linux to serve Web pages. The bug applies to just about every Pentium platform, but it really only affects people that are running computers where you would have people running code on a computer that aren't really trusted," said Hudson. "In an ISP situation, you could have Joe from anywhere. If they get pissed off at you, they are going to do whatever they can," said Hudson. "This bug looks far worse that FPIV [Pentium's notorious floating point bug of some years ago]" said Sam Trenholme, a developer on the BugTraq list. "Intel will probably be forced to undergo an expensive recall." Petz
