CVE-2022-28828

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.
