Direct3D Use After Free RCE Vulnerability

A remote code execution vulnerability exists when the Windows GDI component fails to properly handle objects in memory. 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.

There are multiple ways an attacker could exploit the vulnerability:

  • In a web-based attack scenario, an attacker could host a specially crafted website designed to exploit the 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 or instant 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 designed to exploit the vulnerability and then convince a user to open the document file.

The security update addresses the vulnerability by correcting how the Windows GDI component handles objects in the memory.
