XZ Utils Backdoor

Multiple analyses describe a sophisticated supply‑chain backdoor (CVE‑2024‑3094) in xz-utils 5.6.0/5.6.1 that injects a multi‑stage payload into liblzma to hook OpenSSH pre‑authentication and enable remote code execution, prompting vendor advisories, detection tools, and remediation guidance (patch/downgrade) for affected rolling/unstable Linux distributions.
