This update reverts the\nsecurity fix pending further investigation.\n\nOriginal advisory details:\n\n Simon McVittie discovered that IBus did not enforce appropriate access\n controls on its private D-Bus socket. A local unprivileged user who\n discovers the IBus socket address of another user could exploit this to\n capture the key strokes of the other user.\n","modified":"2026-04-22T10:00:10.657923Z","published":"2019-09-23T13:33:40Z","related":["UBUNTU-CVE-2019-14822"],"references":[{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-4134-2"},{"type":"REPORT","url":"https://launchpad.net/bugs/1844853"}],"affected":[{"package":{"name":"ibus","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/ibus@1.5.11-1ubuntu2.3?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.5.11-1ubuntu2.3"}]}],"versions":["1.5.10-1ubuntu1","1.5.11-1ubuntu1","1.5.11-1ubuntu2","1.5.11-1ubuntu2.1","1.5.11-1ubuntu2.2"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"gir1.2-ibus-1.0","binary_version":"1.5.11-1ubuntu2.3"},{"binary_name":"ibus","binary_version":"1.5.11-1ubuntu2.3"},{"binary_name":"ibus-gtk","binary_version":"1.5.11-1ubuntu2.3"},{"binary_name":"ibus-gtk3","binary_version":"1.5.11-1ubuntu2.3"},{"binary_name":"ibus-wayland","binary_version":"1.5.11-1ubuntu2.3"},{"binary_name":"libibus-1.0-5","binary_version":"1.5.11-1ubuntu2.3"}]},"database_specific":{"cves_map":{"cves":[],"ecosystem":"Ubuntu:16.04:LTS"},"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/usn/USN-4134-2.json"}},{"package":{"name":"ibus","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/ibus@1.5.17-3ubuntu5.2?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.5.17-3ubuntu5.2"}]}],"versions":["1.5.14-2ubuntu1","1.5.14-3ubuntu1","1.5.17-1ubuntu1","1.5.17-3ubuntu1","1.5.17-3ubuntu3","1.5.17-3ubuntu4","1.5.17-3ubuntu5","1.5.17-3ubuntu5.1"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"gir1.2-ibus-1.0","binary_version":"1.5.17-3ubuntu5.2"},{"binary_name":"ibus","binary_version":"1.5.17-3ubuntu5.2"},{"binary_name":"ibus-gtk","binary_version":"1.5.17-3ubuntu5.2"},{"binary_name":"ibus-gtk3","binary_version":"1.5.17-3ubuntu5.2"},{"binary_name":"ibus-wayland","binary_version":"1.5.17-3ubuntu5.2"},{"binary_name":"libibus-1.0-5","binary_version":"1.5.17-3ubuntu5.2"}]},"database_specific":{"cves_map":{"cves":[],"ecosystem":"Ubuntu:18.04:LTS"},"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/usn/USN-4134-2.json"}}],"schema_version":"1.7.5"}
