Red Hat Warns of Backdoor in XZ Tools Impacting Fedora 41 and Rawhide

Red Hat warned users to stop using Fedora 41 or Rawhide due to a backdoor found in XZ compression tools
The backdoor was found in XZ versions 5.6.0 and 5.6.1 and allows unauthorized system access
The malicious code interferes with SSH authentication via systemd to potentially allow remote code execution
Red Hat assigned CVE-2024-3094 to track the issue and reverted Fedora Beta to XZ 5.4.x
CISA also issued an advisory warning developers and users to downgrade XZ and check systems for suspicious activity
