RegreSSHion is a family of security bugs in the OpenSSH software that allows for an attacker to remotely execute code and gain potential root access on a machine running the OpenSSH Server. [ 1 ] [ 2 ] The vulnerability was discovered by the Qualys Threat Research Unit and was disclosed on July 1, 2024.
The issue has been given the Common Vulnerabilities and Exposures number CVE-2024-3094 and has been assigned a CVSS score of 10.0, the highest possible score. [ 5 ] While xz is commonly present in most Linux distributions , at the time of discovery the backdoored version had not yet been widely deployed to production systems, but was present in ...
OpenSSH is not a single computer program, but rather a suite of programs that serve as alternatives to unencrypted protocols like Telnet and FTP. OpenSSH is integrated into several operating systems, namely Microsoft Windows, macOS and most Linux operating systems, [7] [8] while the portable version is available as a package in other systems ...
The address space layout randomization also has vulnerabilities. According to the paper of Shacham et al., [13] the ASLR on 32-bit architectures is limited by the number of bits available for address randomization. Only 16 of the 32 address bits are available for randomization, and 16 bits of address randomization can be defeated by brute force ...
In 2017, two CPU vulnerabilities (dubbed Meltdown and Spectre) were discovered, which can use a cache-based side channel to allow an attacker to leak memory contents of other processes and the operating system itself. A timing attack watches data movement into and out of the CPU or memory on the hardware running the cryptosystem or algorithm ...
Vulnerabilities vary in their ability to be exploited by malicious actors, [3] and the actual risk is dependent on the nature of the vulnerability as well as the value of the surrounding system. [7] Although some vulnerabilities can only be used for denial of service attacks, more dangerous ones allow the attacker to inject and run their own ...
