FAQ: The RegreSSHion vulnerability and GitLab

RegreSSHion (CVE-2024-6387) is a recently identified remote unauthenticated code execution vulnerability in OpenSSH's server (sshd), posing a significant security risk by allowing attackers to execute code as root on glibc-based Linux systems due to a signal handler race condition. While GitLab.com and GitLab Dedicated environments are unaffected due to their use of gitlab-sshd, self-managed GitLab customers may need to apply patches if they maintain the core operating system. The flaw is not easily exploitable in real-world environments due to the complexity and time required for a successful attack, and unpatched environments face a low risk as attackers might opt for easier methods like phishing. To mitigate this risk, GitLab recommends regular patching, strong passwords, multi-factor authentication, and following GitLab Hardening Recommendations, including configuring systems to use gitlab-sshd and adjusting settings to complicate potential exploit attempts. Although the RegreSSHion attack can be devastating if successful, its likelihood in typical internet environments is low, as demonstrated by the difficulty of achieving success even in controlled lab conditions.
