Therefore, we recommend that ESET users keep track of any related patches for their systems and apply them as soon as possible.

However, detection would have an extremely negative impact on the device’s performance and significantly influence user experience it would be a less effective approach than prevention.

These pre-computed results, if not used, are discarded – but, as researchers have shown, there are side-effects left by such precomputation which are not disposed of thoroughly enough and can sometimes be leaked to the potential attacker.Īs stated by the authors of the papers describing the vulnerabilities, there are theoretical ways antivirus could detect the problem. They allow the processor to make better use of time it would have to spend waiting unnecessarily before executing the next instruction to pre-compute further results which may or may not be used in the execution flow. These techniques are called “out-of-order” and “speculative” execution. The Spectre and Meltdown vulnerabilities are bi-products of optimization techniques designed to increase the performance of modern processors. The vulnerabilities affect the microprocessors in the majority of the world’s computers, including mobile devices and cloud networks, and can allow hackers to access the entire contents of a computer’s memory. Apple’s iPhones, iPads and Mac computers are all vulnerable. Many types of computing devices, with many different vendors’ processors and operating systems are susceptible. ESET has found new vulnerabilities called Spectre and Meltdown that affect almost all Intel, AMD and ARM processors, allowing hackers to access a computer’s memory.ĮSET says it is one of the few third-party security solutions already compatible with Microsoft’s emergency patches, released on 3 January, for vulnerabilities called Spectre and Meltdown that affect almost all Intel, AMD and ARM processors.
