Microsoft Windows Type 1 Font Parsing Remote Code Execution Vulnerability (ADV200006)

critical Nessus Plugin ID 134942


The remote Windows host is affected by a font parsing vulnerability.


Two remote code execution vulnerabilities exist in Microsoft Windows when the Windows Adobe Type Manager Library improperly handles a specially-crafted multi-master font - Adobe Type 1 PostScript format. There are multiple ways an attacker could exploit the vulnerability, such as convincing a user to open a specially crafted document or viewing it in the Windows Preview pane.

Note that Microsoft does not recommend that IT administrators running Windows 10 implement the workarounds described in ADV200006. Please see the vendor advisory for more information.


Microsoft has provided additional details and guidance in the ADV200006 advisory.
