Spectre, on the other hand, is a bit more serious. Meltdown, for those unaware, is a flaw in modern Intel processors, which leaves a computer’s kernel memory data – the protected part of a system used to store sensitive information, like passwords – open to prying eyes. More specifically, the build reinforces the barrier that stops savvy hackers from using malicious Javascript code to attack Apple’s in-house Safari browser, in a bid to gain access to the confidential material saved on a device. The firm’s latest patch supersedes an earlier release – which mitigated against the effects of Meltdown on its Mac range, and Spectre on the iPad and iPhone – by introducing protection from browser-based Javascript attacks. Apple has issued important maintenance updates for iOS (11.2.2) and macOS High Sierra (10.13.2), designed to strengthen its software’s defences against the ever-so-scary Meltdown and Spectre chipset vulnerabilities.
