{"id":"DEBIAN-CVE-2026-79992","details":"A flaw was found in Emacs TRAMP. A local attacker could exploit this vulnerability by processing maliciously crafted filenames. This occurs because TRAMP concatenates login arguments without proper sanitization, which are then passed to a local shell. Successful exploitation could lead to arbitrary code execution.","modified":"2026-09-14T17:03:36.170866325Z","published":"2026-08-25T18:18:06.973Z","upstream":["CVE-2026-79992"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-79992"}],"affected":[{"package":{"name":"emacs","ecosystem":"Debian:12","purl":"pkg:deb/debian/emacs?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:28.2+1-15","1:28.2+1-15+deb12u1","1:28.2+1-15+deb12u2","1:28.2+1-15+deb12u3","1:28.2+1-15+deb12u4","1:28.2+1-16","1:29.1+1-1","1:29.1+1-2","1:29.1+1-3","1:29.1+1-4","1:29.1+1-5","1:29.1+1-5~bpo12+1","1:29.2+1-1","1:29.2+1-2","1:29.2+1-2~bpo12+1","1:29.3+1-1","1:29.3+1-2","1:29.3+1-2~bpo12+1","1:29.3+1-3","1:29.3+1-3~bpo12+1","1:29.4+1-1","1:29.4+1-2","1:29.4+1-2~bpo12+1","1:29.4+1-3","1:29.4+1-4","1:29.4+1-4~bpo12+1","1:29.4+1-5","1:29.4+1-6","1:29.4+1-6+alpha","1:30.1+1-1","1:30.1+1-2","1:30.1+1-3","1:30.1+1-3~bpo12+1","1:30.1+1-4","1:30.1+1-4~bpo12+1","1:30.1+1-5","1:30.1+1-5~bpo12+1","1:30.1+1-6","1:30.1+1-6~bpo12+1","1:30.1+1-7","1:30.1+1-8","1:30.1+1-9","1:30.2+1-1","1:30.2+1-10","1:30.2+1-11","1:30.2+1-2","1:30.2+1-3","1:30.2+1-4","1:30.2+1-5","1:30.2+1-6","1:30.2+1-7","1:30.2+1-8","1:30.2+1-9"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-79992.json"}},{"package":{"name":"emacs","ecosystem":"Debian:13","purl":"pkg:deb/debian/emacs?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:30.1+1-6","1:30.1+1-6+deb13u1","1:30.1+1-7","1:30.1+1-8","1:30.1+1-9","1:30.2+1-1","1:30.2+1-10","1:30.2+1-11","1:30.2+1-2","1:30.2+1-3","1:30.2+1-4","1:30.2+1-5","1:30.2+1-6","1:30.2+1-7","1:30.2+1-8","1:30.2+1-9"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-79992.json"}},{"package":{"name":"emacs","ecosystem":"Debian:14","purl":"pkg:deb/debian/emacs?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:30.1+1-6","1:30.1+1-7","1:30.1+1-8","1:30.1+1-9","1:30.2+1-1","1:30.2+1-10","1:30.2+1-11","1:30.2+1-2","1:30.2+1-3","1:30.2+1-4","1:30.2+1-5","1:30.2+1-6","1:30.2+1-7","1:30.2+1-8","1:30.2+1-9"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-79992.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
