The security fix introduced a\nregression when being used with Qt applications. 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.","dates":{"published":"2019-09-23T13:33:40.000Z","modified":"2026-04-22T10:00:10.657Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":null,"severity":"unknown","version":null,"versionLabel":null,"source":null,"vector":null,"computed":false,"selection":"none"},"metrics":[]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[],"affected":[{"vendor":"ubuntu","product":"ibus","name":"ibus","label":"ibus","ecosystem":"Ubuntu","cpePart":null,"purl":"pkg:deb/ubuntu/ibus","purlType":"deb","versions":[{"text":"< 1.5.11-1ubuntu2.3","noFixRecorded":false,"fixedIn":null},{"text":"< 1.5.17-3ubuntu5.2","noFixRecorded":false,"fixedIn":null}],"versionsText":"< 1.5.11-1ubuntu2.3 | < 1.5.17-3ubuntu5.2","eol":null,"hubHref":null}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://ubuntu.com/security/notices/USN-4134-2","label":"ubuntu.com/security/notices/USN-4134-2","hostname":"ubuntu.com","tags":["Advisory"]},{"url":"https://launchpad.net/bugs/1844853","label":"launchpad.net/bugs/1844853","hostname":"launchpad.net","tags":["REPORT"]}],"lineage":{"upstream":[],"downstream":[],"duplicates":[],"related":["CVE-2019-14822"]},"timeline":[{"kind":"published","date":"2019-09-23T13:33:40.000Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-04-22T10:00:10.657Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":0,"level":"minimal","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-20T22:21:50.995Z","stale":false,"partial":false}}
