In February 2024, a malicious backdoor was introduced to the Linux build of the xz utility within the liblzma library in versions 5.6.0 and 5.6.1 by an account using the name "Jia Tan". [b] [4] The backdoor gives an attacker who possesses a specific Ed448 private key remote code execution through OpenSSH on the affected Linux
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 ...
In July 2023 a critical vulnerability in the Zen 2 AMD microarchitecture called Zenbleed was made public. [59] AMD released a microcode update to fix it. [60] In August 2023 a vulnerability in AMD's Zen 1, Zen 2, Zen 3, and Zen 4 microarchitectures called Inception [61] [62] was revealed and assigned CVE-2023-20569. According to AMD it is not ...
[4] [21] It was made public in conjunction with another vulnerability, Meltdown, on 3 January 2018, after the affected hardware vendors had already been made aware of the issue on 1 June 2017. [22] The vulnerability was called Spectre because it was "based on the root cause, speculative execution.
A backdoor may take the form of a hidden part of a program, [7] a separate program (e.g. Back Orifice may subvert the system through a rootkit), code in the firmware of the hardware, [8] or parts of an operating system such as Windows. [9] [10] [11] Trojan horses can be used to create vulnerabilities in a device.
August: Ken Thompson publishes his seminal paper, "Reflections on Trusting Trust", in which he describes how he modified a C compiler so that when used to compile a specific version of the Unix operating system, it inserts a backdoor into the login command, and when used to compile a new copy of itself, it inserts the backdoor insertion code ...
DoublePulsar is a backdoor implant tool developed by the U.S. National Security Agency's (NSA) Equation Group that was leaked by The Shadow Brokers in early 2017. [3] [citation needed] The tool infected more than 200,000 Microsoft Windows computers in only a few weeks, [4] [5] [3] [6] [7] and was used alongside EternalBlue in the May 2017 WannaCry ransomware attack.
Shellshock, also known as Bashdoor, [1] is a family of security bugs [2] in the Unix Bash shell, the first of which was disclosed on 24 September 2014.Shellshock could enable an attacker to cause Bash to execute arbitrary commands and gain unauthorized access [3] to many Internet-facing services, such as web servers, that use Bash to process requests.
