CVE-2022-37383

Information disclosure via unchecked Doc object conversion

Published Mar 29, 2023 · Updated Feb 14, 2025

Out-of-bounds read in Foxit PDF Reader 11.2.1.53537 allows remote attackers to disclose process memory through a malicious PDF. JavaScript actions on a Doc object force a type conversion without validating the object's data type, causing a read past its allocation. The target must open the file or visit a malicious page; code execution requires chaining the disclosure with another vulnerability.
