What is CVE-2025-6642?

A vulnerability exists in PDF-XChange Editor due to improper parsing of U3D files, leading to an out-of-bounds read condition. This flaw allows remote attackers to execute arbitrary code if a user interacts with a maliciously crafted file or webpage. The insufficient validation of user-supplied data leads to potential reading past the allocated memory, making it possible for attackers to execute commands within the context of the affected process. Therefore, caution should be exercised when opening files from untrusted sources.
