Security readout for executives and security teams

This is an old local file-tampering flaw in rcs2log, a utility shipped with Emacs, XEmacs, and possibly other packages. A user who already has local access could abuse temporary-file handling to change files owned by another user. Internet-facing exposure is not indicated. Exposure is most likely on legacy Unix-like systems with multi-user local access and affected rcs2log versions installed. Modern environments are likely exposed only if old Emacs, XEmacs, or bundled rcs2log copies remain in use. Treat this as a legacy hygiene and shared-system risk, not an emergency internet-facing issue. Prioritize if the organization still operates multi-user Unix hosts or old editor packages in production, build, or research environments. Mitigation focus: Inventory systems for Emacs, XEmacs, and standalone or bundled rcs2log copies.; Upgrade XEmacs versions before 21.4 to supported non-affected releases.; Check Emacs and package vendor guidance for the exact fixed rcs2log version..
