{"id":"ALPINE-CVE-2020-12049","details":"An issue was discovered in dbus \u003e= 1.3.0 before 1.12.18. The DBusServer in libdbus, as used in dbus-daemon, leaks file descriptors when a message exceeds the per-message file descriptor limit. A local attacker with access to the D-Bus system bus or another system service's private AF_UNIX socket could use this to make the system service reach its file descriptor limit, denying service to subsequent D-Bus clients.","modified":"2026-09-11T10:17:51.367669460Z","published":"2020-06-08T17:15:09.910Z","upstream":["CVE-2020-12049"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2020-12049"}],"affected":[{"package":{"name":"dbus","ecosystem":"Alpine:v3.10","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.3.0"},{"fixed":"1.12.16-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-12049.json"}},{"package":{"name":"dbus","ecosystem":"Alpine:v3.11","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.3.0"},{"fixed":"1.12.16-r3"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-12049.json"}},{"package":{"name":"dbus","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.3.0"},{"fixed":"1.12.18-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-12049.json"}},{"package":{"name":"dbus","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.3.0"},{"fixed":"1.12.18-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-12049.json"}},{"package":{"name":"dbus","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.3.0"},{"fixed":"1.12.18-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-12049.json"}},{"package":{"name":"dbus","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.3.0"},{"fixed":"1.12.18-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-12049.json"}},{"package":{"name":"dbus","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.3.0"},{"fixed":"1.12.18-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-12049.json"}},{"package":{"name":"dbus","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.3.0"},{"fixed":"1.12.18-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-12049.json"}},{"package":{"name":"dbus","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.3.0"},{"fixed":"1.12.18-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-12049.json"}},{"package":{"name":"dbus","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.3.0"},{"fixed":"1.12.18-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-12049.json"}},{"package":{"name":"dbus","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.3.0"},{"fixed":"1.12.18-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-12049.json"}},{"package":{"name":"dbus","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.3.0"},{"fixed":"1.12.18-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-12049.json"}},{"package":{"name":"dbus","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.3.0"},{"fixed":"1.12.18-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-12049.json"}},{"package":{"name":"dbus","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.3.0"},{"fixed":"1.12.18-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-12049.json"}},{"package":{"name":"dbus","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.3.0"},{"fixed":"1.12.18-r0"}]}],"ecosystem_specific":
