Intel Issues Patches to Fix Wireless Flaws
Intel has released updates to fix at least seven separate security flaws in the low-level software that powers its Centrino wireless devices. The flaws reside in Intel's wireless "device drivers," and are present at such a fundamental level of the operating system that they could be used by bad guys to spread malicious software like a computer worm wirelessly between vulnerable computers without any action on the part of the user.
The Intel Web site has more information on these flaws and includes a tool that people can use to tell whether they need to download and install software updates to fix the problems. I would strongly advise anyone using a laptop with an embedded wireless card to pay a visit to the page and run the tool, as many, many computer manufacturers embed Intel's hardware and software into their machines.
Yesterday, I wrote about a series of flaws security researchers here at Black Hat were able to find in multiple wireless device drivers. While Intel's update appears unrelated to their presentation, these vulnerabilities are quite serious and we are likely to see similar updates in the not-too-distant future from other companies that make these device drivers. Intel said it is currently working with various computer manufacturers to get their word out to their customers as well.
