{"id":"DEBIAN-CVE-2024-53920","details":"In elisp-mode.el in GNU Emacs before 30.1, 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.)","modified":"2026-09-22T08:47:29.440676884Z","published":"2024-11-27T15:15:26.837Z","upstream":["CVE-2024-53920"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2024-53920"}],"affected":[{"package":{"name":"emacs","ecosystem":"Debian:12","purl":"pkg:deb/debian/emacs?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:28.2+1-15+deb12u4"}]}],"versions":["1:28.2+1-15","1:28.2+1-15+deb12u1","1:28.2+1-15+deb12u2","1:28.2+1-15+deb12u3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-53920.json"}},{"package":{"name":"emacs","ecosystem":"Debian:13","purl":"pkg:deb/debian/emacs?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:30.1+1-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-53920.json"}},{"package":{"name":"emacs","ecosystem":"Debian:14","purl":"pkg:deb/debian/emacs?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:30.1+1-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-53920.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
