Arbitrary code execution via PDF parser out-of-bounds write
Published May 13, 2022 · Updated Apr 23, 2025
Adobe FrameMaker 2019u8 and 2020u4 and earlier contain an out-of-bounds write that allows remote attackers to execute arbitrary code via a malicious PDF. The PDF parser writes crafted data past an allocated buffer when a victim opens the file, corrupting process memory and enabling code execution in the current user's context. Exploitation requires user interaction; the attacker must induce the victim to open the malicious document, and the resulting code runs with that user's privileges.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
