Information Disclosure in PDF-XChange Editor due to U3D File Parsing

CVE-2025-6643

What is CVE-2025-6643?

The vulnerability exists in the way PDF-XChange Editor processes U3D file parsing, leading to potential information disclosure. Due to inadequate validation of user-supplied data, an attacker could exploit this flaw by convincing a user to visit a malicious webpage or open a compromised U3D file. Successful exploitation may permit the attacker to read past the bounds of allocated memory segments, resulting in the exposure of sensitive information. This issue, when combined with other vulnerabilities, could allow for further compromises within the user environment.
