CVE-2024-7722Network attack vector

Information disclosure via freed Doc object dereference

Published Aug 21, 2024 · Updated Sep 3, 2024

Use-after-free in Doc object handling in Foxit PDF Reader 2024.1.0.23997 allows remote attackers to disclose process memory via a crafted PDF. The application performs operations on a Doc object without confirming it still exists, dereferencing memory after the object has been freed. Exploitation requires opening a malicious file or visiting a malicious page; the resulting disclosure can support a separate code-execution chain.
