Apple fixes a flaw, Samsung targets gamers, and Facebook tweaks the newsfeed yet again.
I'm Bridget Carey and this is your CNET Update.
If you own any sort of Apple device, whether it's a Mac, desktop or an iPhone or iPad, you need to update your operating system right now to fix a serious encryption bug.
The security flaw known as the "Goto Fail Bug" makes it
really easy for nearby hackers to tap in to your device and read your e-mails, instant messages and spy on any website you visit even online banking sites.
But folks are only at risk when using a public Wi-Fi like at a coffee shop or airport.
But you can patch the problem now by installing the update on Macs that run Mavericks and Mountain Lion versions of the OS X operating system.
The patch for iOS on mobile devices has been available for a few days now.

Moving on to gadget news, Samsung has a new game pad accessory for Android phones.
It hooks onto the phone so you can play games with an Xbox-styled game controller.

You'll start seeing posts in your newsfeed from pages you don't follow.
Facebook thinks you want to see things that you didn't ask to see because it may tag a page that you do care about.
For example, if you like the basketball star Dwight Howard, you may see this post

It's really not that different than what happens now with your friends.
You may see posts that your friends were tagged in from strangers.
