{"id":"DEBIAN-CVE-2018-16888","details":"It was discovered systemd does not correctly check the content of PIDFile files before using it to kill processes. When a service is run from an unprivileged user (e.g. User field set in the service file), a local attacker who is able to write to the PIDFile of the mentioned service may use this flaw to trick systemd into killing other services and/or privileged processes. Versions before v237 are vulnerable.","modified":"2026-09-01T16:04:39.851234013Z","published":"2019-01-14T22:29:00.233Z","upstream":["CVE-2018-16888"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2018-16888"}],"affected":[{"package":{"name":"systemd","ecosystem":"Debian:12","purl":"pkg:deb/debian/systemd?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"237-1"}]}],"ecosystem_specific":{"urgency":"low"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2018-16888.json"}},{"package":{"name":"systemd","ecosystem":"Debian:13","purl":"pkg:deb/debian/systemd?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"237-1"}]}],"ecosystem_specific":{"urgency":"low"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2018-16888.json"}},{"package":{"name":"systemd","ecosystem":"Debian:14","purl":"pkg:deb/debian/systemd?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"237-1"}]}],"ecosystem_specific":{"urgency":"low"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2018-16888.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
