    For owners of mid-2014 or earlier Macs, a new attack against a vulnerability in the UEFI boot script table is worth knowing about but won't affect most customers.

    UEFI - Unified Extensible Firmware Interface *is what the Mac uses to boot from firmware and into the OS X operating system. If you're familiar with BIOS, then this replaced that. At the Chaos Communication Congress (CCC) in 2014, a presentation showed how a vulnerability in the boot script table could be used to rewrite the firmware when a Mac wakes after being in sleep mode. As usual, it's something to be informed about, but for the vast majority of people, nothing to panic about.
