CVE-2020-17423

Remote code execution via ARW heap overflow

Published Feb 9, 2021 · Updated Aug 4, 2024

Foxit Studio Photo 3.6.6.922 contains a heap-based buffer overflow in ARW parsing that lets remote attackers execute arbitrary code via malicious files. The parser copies user-supplied ARW data into a heap buffer without validating its length. Exploitation requires a target user to visit a malicious page or open a crafted file, and code runs in the current process context.
