"Nasty Linux Systemd Security Bug Revealed"
Researchers at the cybersecurity firm Qualys found a new Linux systemd security bug. Systemd is a system and services manager for Linux operating systems. It is the default service manager in many Linux distributions. According to Qualys, the exploitation of the new systemd vulnerability could allow unprivileged users to cause a denial of service via kernel panic. The security hole is said to have arrived in the systemd code in April 2015. It enables attackers to misuse the alloca() function in a way that causes memory corruption, which then allows them to crash systemd and, therefore, the entire operating system. There's no way to solve this problem. Although it is not present in all current Linux distributions, it can be found in most distributions such as the Debian 10 (Buster) and its relatives like Ubuntu and Mint. This article continues to discuss the new Linux systemd security bug that can enable any unprivileged user to crash a Linux system.
