{"id":"CVE-2019-3843","details":"It was discovered that a systemd service that uses DynamicUser property can create a SUID/SGID binary that would be allowed to run as the transient service UID/GID even after the service is terminated. A local attacker may use this flaw to access resources that will be owned by a potentially different service in the future, when the UID/GID will be recycled.","modified":"2026-04-02T02:07:50.415323Z","published":"2019-04-26T21:29:00.360Z","related":["CGA-vmhg-rj6r-p56w","SUSE-SU-2019:1364-1","SUSE-SU-2019:1364-2","openSUSE-SU-2024:11420-1"],"references":[{"type":"WEB","url":"https://lists.apache.org/thread.html/r58af02e294bd07f487e2c64ffc0a29b837db5600e33b6e698b9d696b%40%3Cissues.bookkeeper.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rf4c02775860db415b4955778a131c2795223f61cb8c6a450893651e4%40%3Cissues.bookkeeper.apache.org%3E"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5JXQAKSTMABZ46EVCRMW62DHWYHTTFES/"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/108116"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20190619-0002/"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/4269-1/"},{"type":"FIX","url":"https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-3843"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/systemd/systemd","events":[{"introduced":"0"},{"fixed":"1e5d2d656420d0e755dbcf72aeba3c3aba54e956"},{"introduced":"0"},{"last_affected":"501c92c432c7bef452a2714c29519bdd45281a72"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"242"},{"introduced":"0"},{"last_affected":"30"}]}}],"versions":["001","002","003","004","005","006","007","008","009","010","011","012","013","014","015","016","017","018","019","020","021","022","023","024","025","026","027","028","029","030","031","032","033","034","035","036","037","038","039","040","042","043","044","045","046","047","048","049","050","051","052","053","054","055","056","057","058","059","060","061","062","064","174","175","176","177","178","179","180","181","182","v1","v10","v11","v12","v13","v14","v15","v16","v17","v18","v183","v184","v185","v186","v187","v188","v189","v19","v190","v191","v192","v193","v194","v195","v196","v197","v198","v199","v2","v20","v200","v201","v202","v203","v204","v205","v206","v207","v208","v209","v21","v210","v211","v212","v213","v214","v215","v216","v217","v218","v219","v22","v220","v221","v222","v223","v224","v225","v226","v227","v228","v229","v23","v230","v231","v232","v233","v234","v235","v236","v237","v238","v239","v239-10","v239-11","v239-12","v239-13","v239-13.1","v239-13.2","v239-13.3","v239-13.4","v239-13.5","v239-13.6","v239-13.7","v239-14","v239-15","v239-16","v239-17","v239-18","v239-18.1","v239-18.2","v239-18.3","v239-18.4","v239-18.5","v239-18.6","v239-18.7","v239-18.8","v239-19","v239-20","v239-21","v239-22","v239-23","v239-24","v239-25","v239-26","v239-27","v239-28","v239-29","v239-30","v239-31","v239-31.1","v239-31.2","v239-31.3","v239-31.4","v239-32","v239-33","v239-34","v239-35","v239-36","v239-37","v239-38","v239-39","v239-40","v239-41","v239-41.1","v239-41.2","v239-41.3","v239-42","v239-43","v239-44","v239-45","v239-45.1","v239-45.2","v239-45.3","v239-46","v239-47","v239-48","v239-49","v239-50","v239-8","v239-9","v24","v240","v241","v241-rc1","v241-rc2","v242-rc1","v242-rc2","v242-rc3","v242-rc4","v25","v26","v27","v28","v29","v3","v30","v4","v5","v6","v7","v8","v9"],"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"16.04"}]},{"events":[{"introduced":"0"},{"last_affected":"18.04"}]},{"events":[{"introduced":"0"},{"last_affected":"19.10"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2019-3843.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
