{"id":"DEBIAN-CVE-2026-84233","details":"A flaw was found in rpm. A local attacker could supply a specially crafted `.gem` filename containing RPM macro syntax. When a user or automated workflow invokes `rpmuncompress -x` on this file, the macro expansion occurs during command construction. This allows the attacker to execute arbitrary commands with the privileges of the invoking account, leading to a compromise of confidentiality, integrity, and availability.","modified":"2026-09-14T17:03:37.155690561Z","published":"2026-09-01T15:17:43.853Z","upstream":["CVE-2026-84233"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-84233"}],"affected":[{"package":{"name":"rpm","ecosystem":"Debian:12","purl":"pkg:deb/debian/rpm?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.18.0+dfsg-1","4.18.0+dfsg-1+deb12u1","4.18.2+dfsg-1","4.18.2+dfsg-1.1~exp1","4.18.2+dfsg-2","4.18.2+dfsg-2.1","4.18.2+dfsg-2.1~exp1","4.19.1.1+dfsg-1","4.19.1.1+dfsg-1~exp","4.20.0+dfsg-1","4.20.0+dfsg-2","4.20.0+dfsg-3","4.20.0+dfsg-4","4.20.1+dfsg-1","4.20.1+dfsg-2","4.20.1+dfsg-3","6.0.0-1","6.0.0-2","6.0.1-1","6.1.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-84233.json"}},{"package":{"name":"rpm","ecosystem":"Debian:13","purl":"pkg:deb/debian/rpm?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.20.1+dfsg-3","6.0.0-1","6.0.0-2","6.0.1-1","6.1.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-84233.json"}},{"package":{"name":"rpm","ecosystem":"Debian:14","purl":"pkg:deb/debian/rpm?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.20.1+dfsg-3","6.0.0-1","6.0.0-2","6.0.1-1","6.1.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-84233.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
