Microsoft Windows Adobe Font Manager Library Remote Code Execution Vulnerability

Microsoft · Windows

CVSS 7.8 EPSS 69% no public exploit indexed Fix deadline passed 3 May 2022

What it is

Microsoft Windows Adobe Font Manager Library contains an unspecified vulnerability when handling specially crafted multi-master fonts (Adobe Type 1 PostScript format) that allows for remote code execution for all systems except Windows 10. 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.

Why we say that

  • EPSS puts exploitation in the next 30 days at 69%
  • CISA's federal remediation deadline (2022-05-03) has passed
  • Listed in the CISA Known Exploited Vulnerabilities catalogue

Every line above comes from a named public source. Where the evidence is thin, we say so rather than inventing confidence — see methodology.
