Microsoft’s process for releasing Windows updates addressing Meltdown and Spectre has been a bumpy road, marred by high-profile incompatibility issues with third-party antivirus (AV) software and AMD processors. However, neither are remote execution vulnerabilities-in other words, they don’t allow attackers to run malware. It’s important to note that both vulnerabilities put information disclosure at risk. As such, Spectre is likely to remain an issue for years to come. While operating system and browser updates have helped mitigate the risk of Spectre to some degree, experts agree the only true fix is a hardware update. Intel, ARM, and AMD processors are all reportedly affected by Spectre to some extent, and it poses significant patching problems. Both can potentially allow attackers to extract information from other running processes (ex: stealing login cookies from browsers).

There are two flavors of Spectre - variant 1 (bounds check bypass, CVE-2017-5753) and variant 2 (branch target injection, CVE-2017-5715). It’s enabled by the unintended side effects of speculative execution (something processors do to speed things up by predicting what instructions they’re about to receive and executing them ahead of time). Spectre isn’t so much a specific vulnerability as it’s a new class of attack. Spectre variant 2 (branch target injection CVE-2017-5715) Spectre variant 1 (bounds check bypass - CVE-2017-5753)

Of the two bugs, Meltdown is the easier one to fix, and can largely be addressed with operating system updates. A list of vulnerable ARM processors and mitigations is listed here. No AMD processors are affected by Meltdown. It affects all out-of-order Intel processors released since 1995 with the exception of Itanium and pre-2013 Atoms. Meltdown is a CPU vulnerability that allows a user mode program to access privileged kernel-mode memory.

For more in-depth details see our post, The Meltdown and Spectre CPU Bugs, Explained. To help clear things up, we’ve put together a quick guide that walks through the major updates to operating systems and browsers, explaining how they address Meltdown and/or Spectre, what they specifically don’t address, and any known compatibility or performance issues that have been reported.įor even more info, Bleeping Computer has put together a good list of official advisories, notices, patches, and updates organized by vendor. Things haven’t exactly gone smoothly, with several incompatibility muck ups causing a lot of finger-pointing and frustration. This guide will help.Įver since news of Meltdown and Spectre-two massive CPU vulnerabilities affecting nearly every operating systems and device-hit, vendors have been racing to release updates to mitigate the flaws.
