  "title": "Windows Font Library Remote Code Execution Vulnerability",
  "description": "\u003Cp\u003EA remote code execution vulnerability exists when the Windows font library improperly handles specially crafted fonts.\u003C/p\u003E\n\u003Cp\u003EFor all systems except Windows 10, an attacker who successfully exploited the vulnerability could execute code remotely. For systems running Windows 10, an attacker who successfully exploited the vulnerability could execute code in an AppContainer sandbox context with limited privileges and capabilities. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.\u003C/p\u003E\n\u003Cp\u003EThere are multiple ways an attacker could exploit the vulnerability:\u003C/p\u003E\n\u003Cul\u003E\n\u003Cli\u003EIn 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 Messenger message that takes users to the attacker\u0027s website, or by opening an attachment sent through email.\u003C/li\u003E\n\u003Cli\u003EIn a file sharing attack scenario, an attacker could provide a specially crafted document file that is designed to exploit the vulnerability, and then convince users to open the document file.\u003C/li\u003E\n\u003C/ul\u003E\n\u003Cp\u003EThe security update addresses the vulnerability by correcting how the Windows font library handles embedded fonts.\u003C/p\u003E",
