But according to one expert, the most serious updates appear to involve WebKit, which is the engine that powers Apple’s Safari browser that has been at the center of other recent security loopholes on the device. According to Sean Wright, SME application security lead at Immersive Labs, malicious code could be run that “could be chained with some of the higher level vulnerabilities to lead to a compromise of the entire device” due to specific security gaps in WebKit. “This is pretty much as bad as it gets,” he told Forbes.

But even if you don’t have an iPhone, the update also affects other popular Apple products. The latest release includes new software for iPad, Apple Watch, AppleTV, and Mac computers.
