CVE-2024-8822

Information disclosure via unchecked U3D buffer read

Published Nov 22, 2024 · Updated Nov 23, 2024

Out-of-bounds read in U3D parsing in PDF-XChange Editor 10.3.0.386 allows remote attackers to disclose process memory via a crafted file. The U3D parser fails to validate user-supplied structure data before reading past the end of an allocated buffer. Exploitation requires opening a malicious file or visiting a malicious page; this flaw discloses data, while code execution requires another vulnerability.
