Win32k Graphics Remote Code Execution Vulnerability - CVE-2019-1441

oval:org.cisecurity:def:6747

A remote code execution vulnerability exists when the Windows font library improperly handles specially crafted embedded fonts. An attacker who successfully exploited this 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. There are multiple ways an attacker could exploit this vulnerability. In a web-based attack scenario an attacker could host a specially crafted website that is designed to exploit this vulnerability and then convince a user 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 message or in an 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 this vulnerability and then convince a user to open the document file. The security update addresses the vulnerability by correcting how the Windows font library handles embedded fonts.
