CVE-2024-30204

Denial of service via untrusted LaTeX previews

Published Mar 25, 2024 · Updated Nov 4, 2024

Improper default permissions in GNU Emacs before 29.3 allow attackers to interrupt service through a crafted e-mail attachment. The org-latex-preview function generates a preview even when untrusted-content marks the attachment as risky, invoking the LaTeX toolchain on its contents. Exploitation requires a user to open the attachment in an Emacs mail client that renders the preview; the documented consequence is denial of service only.
