The two types of attacks falling under the umbrella of Spectre, according to the researchers that discovered them, break the isolation between applications and trick otherwise error-free programs into leaking sensitive information.
The Spectre that will haunt CPUs for years to come
#SPECTRE MEANING SOFTWARE#
Intel, AMD and other vendors are also releasing firmware updates that will work with OS and software patches to rectify the vulnerability. This is a fundamental change to how the kernel’s memory management works, one that has proven controversial due to estimates that machines applying them would take a 5 to 30% speed hit.Ĭloud providers have taken Meltdown seriously as well, with Amazon Web Services, Google Cloud, and Microsoft Azure all deploying patches against it despite no clear indication that this type of attack could be used against them.
#SPECTRE MEANING WINDOWS#
watchOS was their only product not affected by the flaw.įor Windows and Linux, patches took a Kernel Page-Table Isolation or KPTI approach, by splitting page tables, until now shared between user and kernel space, into two sets of tables, one for each side.
Apple has already partially done it through the iOS 11.2, macOS 10.13.2, and tvOS 11.2 updates by altering existing programming requirements related to the kernel memory data and more fixes will be added to future updates. Luckily, Meltdown is a vulnerability that can be fixed through patching and some of the industry’s biggest players have been preparing for it since security researchers first warned them of it in June 2017. It does this by overcoming the kernel space/user space memory isolation barrier of x86 architecture and exploiting side-channel information made available by the cache after speculative execution of a prepared instruction stream executed out-of-order. Meltdown can be exploited by normal programs, such as JavaScript in web browsers and database applications, to read the contents of private kernel memory. Meltdown, is the flaw initially reported by the Register, which is known to affect Intel CPUs manufactured since 1995, except Itanium server chips and pre-2013 Atom processors as well as the ARM Cortex-A75. What is Meltdown and how can it be fixed? Google had identified and informed affected companies about the possibility of Spectre attacks as early as June 2017 and Meltdown towards the end of July 2017, but chose not to make the information public to allow companies to build patches before hackers got wind of the vulnerabilities. These were dubbed Spectre (variant 1 and 2) and Meltdown (variant 3). Since the initial news broke, several independent teams of academic and industry security researchers from around the world, among them Google’s Zero Project, confirmed they have identified three possible attacks that could exploit processors’ design security flaws. The news sent Intel stock plummeting and the cybersercurity community into a panic as further details of the extent of the vulnerability were revealed.
