SWAPGS, also known as Spectre variant 1, is a computer security vulnerability that utilizes the branch prediction used in modern microprocessors. [1] [2] [3] Most processors use a form of speculative execution, this feature allows the processors to make educated guesses about the instructions that will most likely need to be executed in the near future.
Meltdown exploits a race condition, inherent in the design of many modern CPUs.This occurs between memory access and privilege checking during instruction processing. . Additionally, combined with a cache side-channel attack, this vulnerability allows a process to bypass the normal privilege checks that isolate the exploit process from accessing data belonging to the operating system and other ...
Duqu is a collection of computer malware discovered on 1 September 2011, thought by Kaspersky Labs to be related to the Stuxnet worm [1] and to have been created by Unit 8200. [2] [3] Duqu has exploited Microsoft Windows's zero-day vulnerability.
Speculative Store Bypass (SSB) (CVE-2018-3639) is the name given to a hardware security vulnerability and its exploitation that takes advantage of speculative execution in a similar way to the Meltdown and Spectre security vulnerabilities. [1] It affects the ARM, AMD and Intel families of processors.
Linux kernel developers chose not to add mitigations citing performance concerns. [72] The Xen hypervisor project released patches to mitigate the vulnerability but they are not enabled by default. [73] Also in March 2024, a vulnerability in Intel Atom processors called Register File Data Sampling (RFDS) was revealed. [74] It was assigned CVE ...
In 2014, the FireEye Labs team identified two new zero-day vulnerabilities – CVE-2014–4148 and CVE-2014–4113 – as part of limited, targeted attacks against major corporations. Both zero-days exploit the Windows kernel. Microsoft addressed the vulnerabilities in the October 2014 Security Bulletin. [48]
The award for best privilege escalation bug went to Mateusz Jurczyk ("j00ru") for a vulnerability in the Windows kernel that affected all 32-bit versions of Windows. [40] [41] The award for most innovative research went to Travis Goodspeed for a way to send network packets that would inject additional packets. [40] [41]
It was a high-volume mailing list, with as many as 776 posts in a month, [1] and almost all new security vulnerabilities were discussed on the list in its early days. The forum provided a vehicle for anyone to disclose and discuss computer vulnerabilities , including security researchers and product vendors.
