I became overwhelmed and went into meltdown. Has Meltdown or Spectre been abused in the wild? At the moment, it is unclear whether AMD processors are also affected by Meltdown. Currently, we have only verified Meltdown on Intel processors. Meltdown exploits a race condition , inherent in the design of many modern CPUs. On 8 October , Intel is reported to have added hardware and firmware mitigations regarding Spectre and Meltdown vulnerabilities to its latest processors. The company also announced it had developed Intel Microcode workarounds for processors dating back to , and that it had plans to develop them for most processors dating back to including the Core 2 Duo ; [29] [30] however, a month later in April , it announced it was backing off that plan for a number of processor families and that no processor earlier than would have a patch available.

On 14 November , security researcher Alex Ionescu publicly mentioned changes in the new version of Windows 10 that would cause some speed degradation without explaining the necessity for the changes, just referring to similar changes in Linux. Please tell us where you read or heard it including the quote, if possible. Meltdown and Spectre work on personal computers, mobile devices, and in the cloud. It involves the following ingredients, the person must be just about black out drunk, and they do something that is completely ridiculous such as kick a car door in, break items, cock block their mates, vomit uncontrollably and for it to a true melt down there needs to be tears by the perpetrator. Name that government! In fact, the safety checks of said best practices actually increase the attack surface and may make applications more susceptible to Spectre Spectre is harder to exploit than Meltdown, but it is also harder to mitigate. Oct 3 Word of the Day. While programs are typically not permitted to read data from other programs, a malicious program can exploit Meltdown and Spectre to get hold of secrets stored in the memory of other running programs. The impact of Meltdown depends on the design of the CPU, the design of the operating system specifically how it uses memory paging , and the ability of a malicious party to get any code run on that system, as well as the value of any data it could read if able to execute. It was disclosed in conjunction with another exploit, Spectre , with which it shares some, but not all characteristics. Is Singular 'They' a Better Choice? Get Word of the Day daily email!

Ubuntu Wiki. The awkward case of 'his or her'. They provide the basis for most modern operating systems and processors. Spectre is harder to exploit than Meltdown, but it is also harder to mitigate. If your system is affected, our proof-of- concept exploit can read the memory content of your computer. Since many operating systems map physical memory, kernel processes, and other running user space processes into the address space of every process, Meltdown effectively makes it possible for a rogue process to read any physical, kernel or other processes' mapped memory—regardless of whether it should be able to do so. Probably not. We would like to thank Intel for awarding us with a bug bounty for the responsible disclosure process, and their professional handling of this issue through communicating a clear timeline and connecting all involved researchers. Unlike usual malware, Meltdown and Spectre are hard to distinguish from regular benign applications. Meltdown and Spectre exploit critical vulnerabilities in modern processors.

Microsoft released an emergency update to Windows 10 , 8. Is there more technical information about Meltdown and Spectre? The attack can reveal the content of any memory that is mapped into a user address space, even if otherwise protected. Who reported Meltdown? For a more technical discussion we refer to the papers Meltdown and Spectre Why is it called Meltdown? Four widely used features are particularly relevant to Meltdown:. Security Advisory. Retrieved — via Twitter. Unlike usual malware, Meltdown and Spectre are hard to distinguish from regular benign applications. Security Blog. Meltdown Meltdown breaks the most fundamental isolation between user applications and the operating system. Meltdown uses this technique in sequence to read every address of interest at high speed, and depending on other running processes, the result may contain passwords, encryption data, and any other sensitive information, from any address of any process that exists in its memory map. Meltdown and Spectre Vulnerabilities in modern computers leak passwords and sensitive data. The vulnerability does not affect AMD microprocessors. On 8 October , Intel is reported to have added hardware and firmware mitigations regarding Spectre and Meltdown vulnerabilities to its latest processors.
