An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.\nTo exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take control over an affected system.\nThe update addresses the vulnerability by correcting how Windows handles calls to ALPC.","published":"2019-06-12T14:29:02.000Z","lastModified":"2026-06-17T02:09:16.000Z","status":"Modified","sourceIdentifier":"secure@microsoft.com","cvss":{"version":"3.0","score":7.8,"severity":"HIGH","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":[],"affected":["microsoft/windows 10","microsoft/windows 7","microsoft/windows 8.1","microsoft/windows rt 8.1","microsoft/windows server 2008","microsoft/windows server 2012","microsoft/windows server 2016","microsoft/windows server 2019"],"epss":{"score":0.02373,"percentile":0.83762,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":1,"verified":true,"firstPublished":"2019-06-24","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":47029,"kind":"exploit","title":"Microsoft Windows Font Cache Service - Insecure Sections Privilege Escalation","url":"https://www.exploit-db.com/exploits/47029","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/windows/dos/47029.txt","file":"exploits/windows/dos/47029.txt","published":"2019-06-24","added":"2019-06-24","updated":"2019-06-24","author":"Google Security Research","type":"dos","platform":"windows","port":null,"verified":true,"codes":["CVE-2019-0943"],"tags":null,"aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":"https://bugs.chromium.org/p/project-zero/issues/detail?id=1800"}]},"verdict":{"level":"urgent","text":"A public exploit is published in Exploit-DB (verified) and the impact is high, while EPSS rates exploitation at 2.4%.
