Code execution via font-parser out-of-bounds write
Published May 13, 2022 · Updated Apr 23, 2025
Out-of-bounds write in Adobe FrameMaker 2019 Update 8 and earlier and 2020 Update 4 and earlier allows attackers to execute code. The font parser writes beyond an allocated buffer while processing attacker-controlled font data in a crafted document. Execution occurs in the current user's context only after the user opens the malicious file.
