OTA WiFi vulnerability - what can be done?
This Chip is common in many Phones. The details of the exploit are sufficiently well known as are 1000's of others, the chance of the average person getting hit is low (unless you work somewhere interesting and keep interesting Info on your Devices - Computer, Tablet, Phone, even some TV's are spying).

Partial List of affected Phones with this Chipset: Nexus 5, 6 and 6P, most Samsung flagship devices, and all iPhones since the iPhone 4. 

So many are affected. It someone were so inclined they could own any Device with this Chipset within WiFi range - chances of it being your Device is remote, so don't lose sleep just Update (if you're really worried).

Updating to the newest Firmware and Software is almost always the correct answer to this problem - rarely new Updates introduce worse vulnerabilities.

So, always Update. It's the only Solution. This one Hack is not the only thing affecting your various Devices. Updating prevents all but Day-0 and the as yet unrepaired Bugs. If it's worth it for your Boss to pay let them know.
