{"id":"DEBIAN-CVE-2018-6536","details":"An issue was discovered in Icinga 2.x through 2.8.1. The daemon creates an icinga2.pid file after dropping privileges to a non-root account, which might allow local users to kill arbitrary processes by leveraging access to this non-root account for icinga2.pid modification before a root script executes a \"kill `cat /pathname/icinga2.pid`\" command, as demonstrated by icinga2.init.d.cmake.","modified":"2026-09-01T20:04:00.065379312Z","published":"2018-02-02T09:29:00.367Z","upstream":["CVE-2018-6536"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2018-6536"}],"affected":[{"package":{"name":"icinga2","ecosystem":"Debian:12","purl":"pkg:deb/debian/icinga2?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.8.4-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2018-6536.json"}},{"package":{"name":"icinga2","ecosystem":"Debian:13","purl":"pkg:deb/debian/icinga2?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.8.4-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2018-6536.json"}},{"package":{"name":"icinga2","ecosystem":"Debian:14","purl":"pkg:deb/debian/icinga2?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.8.4-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2018-6536.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
