{"id":"CVE-2018-16865","details":"An allocation of memory without limits, that could result in the stack clashing with another memory region, was discovered in systemd-journald when many entries are sent to the journal socket. A local attacker, or a remote one if systemd-journal-remote is used, may use this flaw to crash systemd-journald or execute code with journald privileges. Versions through v240 are vulnerable.","modified":"2026-04-10T04:06:51.654331Z","published":"2019-01-11T21:29:00.257Z","related":["CGA-h5q7-7m3r-hf35","SUSE-SU-2019:0053-1","SUSE-SU-2019:0054-1","SUSE-SU-2019:0054-2","SUSE-SU-2019:0135-1","SUSE-SU-2019:0137-1","openSUSE-SU-2019:0098-1","openSUSE-SU-2024:11420-1"],"references":[{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2021/07/20/2"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2402"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/3855-1/"},{"type":"ADVISORY","url":"http://packetstormsecurity.com/files/152841/System-Down-A-systemd-journald-Exploit.html"},{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2019/05/10/4"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/106525"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHBA-2019:0327"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:0204"},{"type":"ADVISORY","url":"https://www.debian.org/security/2019/dsa-4367"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:0049"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:0271"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:0342"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:0361"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2019/01/msg00016.html"},{"type":"ADVISORY","url":"https://seclists.org/bugtraq/2019/May/25"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/201903-07"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20190117-0001/"},{"type":"ADVISORY","url":"http://seclists.org/fulldisclosure/2019/May/21"},{"type":"FIX","url":"https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16865"},{"type":"FIX","url":"https://www.oracle.com/technetwork/security-advisory/cpuapr2019-5072813.html"},{"type":"EVIDENCE","url":"https://www.qualys.com/2019/01/09/system-down/system-down.txt"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/systemd/systemd","events":[{"introduced":"0"},{"last_affected":"1742aae2aa8cd33897250d6fcfbe10928e43eb2f"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"240"}]}}],"versions":["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","v24","v240","v25","v26","v27","v28","v29","v3","v30","v31","v32","v33","v34","v35","v36","v37","v38","v39","v4","v40","v41","v42","v43","v44","v5","v6","v7","v8","v9"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2018-16865.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"7.0"}]},{"events":[{"introduced":"0"},{"last_affected":"7.0"}]},{"events":[{"introduced":"0"},{"last_affected":"7.3"}]},{"events":[{"introduced":"0"},{"last_affected":"7.6"}]},{"events":[{"introduced":"0"},{"last_affected":"7.5"}]},{"events":[{"introduced":"0"},{"last_affected":"7.6"}]},{"events":[{"introduced":"0"},{"last_affected":"7.3"}]},{"events":[{"introduced":"0"},{"last_affected":"7.6"}]},{"events":[{"introduced":"0"},{"last_affected":"7.0"}]},{"events":[{"introduced":"0"},{"last_affected":"8.0"}]},{"events":[{"introduced":"0"},{"last_affected":"9.0"}]},{"events":[{"introduced":"0"},{"last_affected":"16.04"}]},{"events":[{"introduced":"0"},{"last_affected":"18.04"}]},{"events":[{"introduced":"0"},{"last_affected":"18.10"}]},{"events":[{"introduced":"0"},{"last_affected":"8.0.0"}]},{"events":[{"introduced":"0"},{"last_affected":"8.1.0"}]},{"events":[{"introduced":"0"},{"last_affected":"8.2.0"}]},{"events":[{"introduced":"0"},{"last_affected":"3.0.0"}]},{"events":[{"introduced":"0"},{"last_affected":"3.1.0"}]}]}}],"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"}]}
