After the announcement that Intel and ARM processors are vulnerable to the “Meltdown” and “Spectre” hacks, Apple has now confirmed that all iOS and Mac processors are susceptible to the flaws, but it has already issued some “mitigations” for the flaws in the most recent iOS and macOS releases. After assuring users that even more fixes are on the way to deal with any other possible exploits, Apple also says that it’s not aware of any current exploits “impacting customers at this time.” Apple then cautioned users that “since exploiting many of these issues requires a malicious app to be loaded on your Mac or iOS device, we recommend downloading software only from trusted sources such as the App Store.”
“Apple has already released mitigations in iOS 11.2, macOS 10.13.2, and tvOS 11.2 to help defend against Meltdown” the company announced. “Apple Watch is not affected by Meltdown. In the coming days we plan to release mitigations in Safari to help defend against Spectre. We continue to develop and test further mitigations for these issues and will release them in upcoming updates of iOS, macOS, tvOS, and watchOS.
