{"cve":"CVE-2019-1144","nvd":{"published":"2019-08-14T21:15:14.423","modified":"2026-06-17T02:27:55.337","status":"Modified","description":"A remote code execution vulnerability exists when the Windows font library improperly handles specially crafted embedded fonts. An attacker who successfully exploited the vulnerability could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.\nThere are multiple ways an attacker could exploit the vulnerability:\n\nIn a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit the vulnerability and then convince users to view the website. An attacker would have no way to force users to view the attacker-controlled content. Instead, an attacker would have to convince users to take action, typically by getting them to click a link in an email or instant message that takes users to the attacker's website, or by opening an attachment sent through email.\nIn a file-sharing attack scenario, an attacker could provide a specially crafted document file designed to exploit the vulnerability and then convince users to open the document file.\n\nThe security update addresses the vulnerability by correcting how the Windows font library handles embedded fonts.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-415"],"references":["http://packetstormsecurity.com/files/154085/Microsoft-Font-Subsetting-DLL-MergeFormat12Cmap-MakeFormat12MergedGlyphList-Double-Free.html","https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-1144","http://packetstormsecurity.com/files/154085/Microsoft-Font-Subsetting-DLL-MergeFormat12Cmap-MakeFormat12MergedGlyphList-Double-Free.html","https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-1144"],"products":["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"],"source":"nvd","synced_at":"2026-10-19T20:58:11.797917892+00:00"},"epss":{"cve":"CVE-2019-1144","score":0.13055,"percentile":0.96346,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
