URL: https://advisories.mageia.org/MGASA-2024-0397.html
Type: security
Affected Mageia releases: 9
CVE: CVE-2024-53920

In elisp-mode.el in GNU Emacs through 30.0.92, a user who chooses to
invoke elisp-completion-at-point (for code completion) on untrusted
Emacs Lisp source code can trigger unsafe Lisp macro expansion that
allows attackers to execute arbitrary code. (This unsafe expansion also
occurs if a user chooses to enable on-the-fly diagnosis that byte
compiles untrusted Emacs Lisp source code). (CVE-2024-53920)
