Windows Font Library Remote Code Execution Vulnerability - CVE-2020-1436

oval:org.cisecurity:def:7985

A remote code execution vulnerability exists when the Windows font library improperly handles specially crafted fonts. For 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. There are multiple ways an attacker could exploit the vulnerability: In 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's website or by opening an attachment sent through email. In 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. The security update addresses the vulnerability by correcting how the Windows font library handles embedded fonts.
