Apple has released an update for its mobile operating system, iOS 9.3.4, which fixes a memory corruption issue that could be exploited “to execute arbitrary code with kernel privileges.” The update blocks a jailbreak bug known as IOMobileFrameBuffer.
Please check your iOS device to ensure it is fully updated and patched. This is done under Settings -> General -> Software Update.
If you have questions about updating your iOS device, please contact the Call Center.
