Remotely executable Wi-Fi bug found in Linux (ComputerWorld)

ComputerWorld reports on an exploitable bug in the MadWi-Fi Linux kernel device driver for Atheros-based Wi-Fi chipsets. "A bug has been found in a major Linux Wi-Fi driver that can allow an attacker to take control of a laptop -- even when it is not on a Wi-Fi network. There have not been many Linux Wi-Fi device drivers, and this is apparently the first remotely executable Wi-Fi bug. It affects the widely used MadWi-Fi Linux kernel device driver for Atheros-based Wi-Fi chipsets, according to Laurent Butti, a researcher from France Telecom Orange, who found the flaw and released the information in a presentation at last month's Black Hat conference in Amsterdam."

madwifi driver doesn't exist in linux kernel, it's EXTERNAL driver. It's like saying ,,major flaw found in Windows'' and pointing to ati driver.

madwifi.org provides some insight:
http://madwifi.org/wiki/news/20070416/no-known-security-i...

To summarize:
- The security hole was found _on_ Linux, not "*in* Linux", since madwifi is not included in the mainline kernel
- The security hole is known for 4 months and it was fixed (in version 0.9.2.1) before it was publicly announced

So, if the fix version (0.9.2.1) is correct, this means that this was fixed on my Gentoo-powered laptop on Sunday December 10, 2006. I'd like to think that the major distros fixed it within a month or so of that release. So why is this news now?

If it is because it *wasn't* in major distros package DBs (in stable), then why not?

Because it sells subscriptions to the credulous?

Who, ComputerWorld, or the major commercial distributions, or both? ;)

I don't know about other distros, but Ubuntu dealt with this back in January:

Just for the record, as they say...

This was fixed in Debian back in december 2006.
http://packages.debian.org/changelogs/pool/non-free/m/mad...

(Seems that the fixed package took the unstable -> testing route,
as madwifi wasn't included in Sarge that was the stable distribution
back then.)

Absolutely. The point being it's much ado about nothing much any more.
