Windows Adobe Type Manager Library RCE Vulnerability
Actively exploited in the wild. Patch or mitigate immediately — don't wait for a maintenance window.
An unauthenticated attacker, remotely over the network, if a user is tricked into opening a malicious file or link, can fully compromise the system — steal data, tamper with it and take it offline.
A remote code execution vulnerability exists in Microsoft Windows when the Windows Adobe Type Manager Library improperly handles a specially-crafted multi-master font - Adobe Type 1 PostScript format.For all systems except Windows 10, an attacker who successfully exploited the vulnerability could execute code remotely, aka 'Adobe Font Manager Library Remote Code Execution Vulnerability'. This CVE ID is unique from CVE-2020-0938.

Generated by Wavense from the CVE record — an immediate mitigation and the permanent fix.
As an interim measure, disable the 'Preview Pane' and 'Details Pane' in Windows Explorer to prevent automatic font rendering. Consider restricting SMB traffic (port 445) at network borders and implement enhanced endpoint detection to monitor for suspicious processes or network connections.
The permanent fix involves installing the security updates released by Microsoft for all affected Windows versions, specifically those prior to Windows 10. These patches correctly address the vulnerability in the Adobe Type Manager Library, eliminating the remote code execution flaw.
An attacker could achieve remote code execution on vulnerable Windows systems (excluding Windows 10) by leveraging a specially-crafted font. This allows full control over the compromised machine, potentially leading to data theft, system disruption, and unauthorized lateral movement within the enterprise network.
