{"id":"UBUNTU-CVE-2023-34969","details":"D-Bus before 1.15.6 sometimes allows unprivileged users to crash dbus-daemon. If a privileged user with control over the dbus-daemon is using the org.freedesktop.DBus.Monitoring interface to monitor message bus traffic, then an unprivileged user with the ability to connect to the same dbus-daemon can cause a dbus-daemon crash under some circumstances via an unreplyable message. When done on the well-known system bus, this is a denial-of-service vulnerability. The fixed versions are 1.12.28, 1.14.8, and 1.15.6.","modified":"2026-04-22T16:47:10.795307Z","published":"2023-06-08T03:15:00Z","related":["USN-6372-1"],"upstream":["CVE-2023-34969"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-34969"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6372-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2023-34969"}],"affected":[{"package":{"name":"dbus","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/dbus@1.10.6-1ubuntu3.6+esm3?arch=source&distro=esm-infra/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.10.6-1ubuntu3.6+esm3"}]}],"versions":["1.10.0-1ubuntu1","1.10.4-1ubuntu2","1.10.6-1ubuntu1","1.10.6-1ubuntu2","1.10.6-1ubuntu3","1.10.6-1ubuntu3.1","1.10.6-1ubuntu3.3","1.10.6-1ubuntu3.4","1.10.6-1ubuntu3.5","1.10.6-1ubuntu3.6","1.10.6-1ubuntu3.6+esm1","1.10.6-1ubuntu3.6+esm2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.10.6-1ubuntu3.6+esm3","binary_name":"dbus"},{"binary_version":"1.10.6-1ubuntu3.6+esm3","binary_name":"dbus-tests"},{"binary_version":"1.10.6-1ubuntu3.6+esm3","binary_name":"dbus-user-session"},{"binary_version":"1.10.6-1ubuntu3.6+esm3","binary_name":"dbus-x11"},{"binary_version":"1.10.6-1ubuntu3.6+esm3","binary_name":"libdbus-1-3"}],"availability":"Available with Ubuntu Pro (Infra-only): https://ubuntu.com/pro"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-34969.json"}},{"package":{"name":"dbus","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/dbus@1.12.2-1ubuntu1.4?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.10.22-1ubuntu1","1.12.0-1ubuntu1","1.12.2-1ubuntu1","1.12.2-1ubuntu1.1","1.12.2-1ubuntu1.2","1.12.2-1ubuntu1.3","1.12.2-1ubuntu1.4"],"ecosystem_specific":{"binaries":[{"binary_version":"1.12.2-1ubuntu1.4","binary_name":"dbus"},{"binary_version":"1.12.2-1ubuntu1.4","binary_name":"dbus-tests"},{"binary_version":"1.12.2-1ubuntu1.4","binary_name":"dbus-user-session"},{"binary_version":"1.12.2-1ubuntu1.4","binary_name":"dbus-x11"},{"binary_version":"1.12.2-1ubuntu1.4","binary_name":"libdbus-1-3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-34969.json"}},{"package":{"name":"dbus","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/dbus@1.12.16-2ubuntu2.3?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.12.14-1ubuntu2","1.12.16-2ubuntu1","1.12.16-2ubuntu2","1.12.16-2ubuntu2.1","1.12.16-2ubuntu2.2","1.12.16-2ubuntu2.3"],"ecosystem_specific":{"binaries":[{"binary_version":"1.12.16-2ubuntu2.3","binary_name":"dbus"},{"binary_version":"1.12.16-2ubuntu2.3","binary_name":"dbus-tests"},{"binary_version":"1.12.16-2ubuntu2.3","binary_name":"dbus-user-session"},{"binary_version":"1.12.16-2ubuntu2.3","binary_name":"dbus-x11"},{"binary_version":"1.12.16-2ubuntu2.3","binary_name":"libdbus-1-3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-34969.json"}},{"package":{"name":"dbus","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/dbus@1.12.20-2ubuntu4.1?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.12.20-2ubuntu2","1.12.20-2ubuntu3","1.12.20-2ubuntu4","1.12.20-2ubuntu4.1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.12.20-2ubuntu4.1","binary_name":"dbus"},{"binary_version":"1.12.20-2ubuntu4.1","binary_name":"dbus-tests"},{"binary_version":"1.12.20-2ubuntu4.1","binary_name":"dbus-user-session"},{"binary_version":"1.12.20-2ubuntu4.1","binary_name":"dbus-x11"},{"binary_version":"1.12.20-2ubuntu4.1","binary_name":"libdbus-1-3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-34969.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"low"}]}
