CVE-2022-35677

Arbitrary code execution via SVG buffer overflow

Published Aug 11, 2022 · Updated Apr 23, 2025

Heap overflow in Adobe FrameMaker 2019 Update 8 and earlier and 2020 Update 4 and earlier allows remote attackers to execute arbitrary code. The SVG parser fails to validate the length of user-supplied data before copying it into a fixed-length heap buffer. Exploitation requires a user to open a malicious file or visit a malicious page, after which code runs in the current process and user context.
