{"id":"ALPINE-CVE-2019-12749","details":"dbus before 1.10.28, 1.12.x before 1.12.16, and 1.13.x before 1.13.12, as used in DBusServer in Canonical Upstart in Ubuntu 14.04 (and in some, less common, uses of dbus-daemon), allows cookie spoofing because of symlink mishandling in the reference implementation of DBUS_COOKIE_SHA1 in the libdbus library. (This only affects the DBUS_COOKIE_SHA1 authentication mechanism.) A malicious client with write access to its own home directory could manipulate a ~/.dbus-keyrings symlink to cause a DBusServer with a different uid to read and write in unintended locations. In the worst case, this could result in the DBusServer reusing a cookie that is known to the malicious client, and treating that cookie as evidence that a subsequent client connection came from an attacker-chosen uid, allowing authentication bypass.","modified":"2026-09-09T06:17:50.056849913Z","published":"2019-06-11T17:29:00.517Z","upstream":["CVE-2019-12749"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2019-12749"}],"affected":[{"package":{"name":"dbus","ecosystem":"Alpine:v3.10","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.12.0"},{"fixed":"1.12.16-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-12749.json"}},{"package":{"name":"dbus","ecosystem":"Alpine:v3.11","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.12.0"},{"fixed":"1.12.16-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-12749.json"}},{"package":{"name":"dbus","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.12.0"},{"fixed":"1.12.16-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-12749.json"}},{"package":{"name":"dbus","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.12.0"},{"fixed":"1.12.16-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-12749.json"}},{"package":{"name":"dbus","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.12.0"},{"fixed":"1.12.16-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-12749.json"}},{"package":{"name":"dbus","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.12.0"},{"fixed":"1.12.16-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-12749.json"}},{"package":{"name":"dbus","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.12.0"},{"fixed":"1.12.16-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-12749.json"}},{"package":{"name":"dbus","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.12.0"},{"fixed":"1.12.16-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-12749.json"}},{"package":{"name":"dbus","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.12.0"},{"fixed":"1.12.16-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-12749.json"}},{"package":{"name":"dbus","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.12.0"},{"fixed":"1.12.16-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-12749.json"}},{"package":{"name":"dbus","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.12.0"},{"fixed":"1.12.16-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-12749.json"}},{"package":{"name":"dbus","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.12.0"},{"fixed":"1.12.16-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-12749.json"}},{"package":{"name":"dbus","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.12.0"},{"fixed":"1.12.16-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-12749.json"}},{"package":{"name":"dbus","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/dbus?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.12.0"},{"fixed":"1.12.16-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-12749.json"}},{"package":{"name":"dbus","ecosystem":"Alpine:v3.24","purl":"pkg:a
