Millions of routers are at risk

Your home router probably doesn't get much attention. After you set it up and secured it (you secured it, right?), you probably haven't thought much about it. It's just chugging along quietly in the background keeping your gadgets securely connected to each other and the Internet.

Unfortunately, your router might not be a secure as you'd hope. Hot off the presses is a report about a security flaw built into millions of home routers. This isn't the first major router security flaw, but it could be the worst so far.

The flaw comes courtesy of a bit of code called NetUSB. NetUSB lets you share the information on USB gadgets over a network simply by plugging the gadget into your router.

Unfortunately, the company that developed NetUSB left in a very basic flaw. It's called a "stack buffer overflow," and it really hasn't been a security problem in most programs since the '90s.

I won't bore you with technical details, but the basics are that a hacker can send a large amount of information to a specific port on your router and crash it. The crash can either be to knock you off the Internet, or the hacker can use the crash to run their own code.
