CVE-2024-30335

Information disclosure via AcroForm Annotation out-of-bounds read

Published Apr 2, 2024 · Updated Aug 2, 2024

Out-of-bounds read in Foxit PDF Reader and PDF Editor through 2023.3.0 allows remote attackers to disclose process memory via a crafted PDF. The AcroForm Annotation handler fails to validate user-supplied object data before reading beyond the end of an allocated buffer. Exploitation requires a user to open the malicious file or visit a page that supplies it; the read exposes data and supports code execution only when chained with another flaw.
