CVE-2025-0908
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedPDF-XChange Editor U3D File Parsing Out-Of-Bounds Read Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of PDF-XChange Editor. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of U3D files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process. Was ZDI-CAN-25557.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceAn out-of-bounds read vulnerability in PDF-XChange Editor's U3D file parser allows reading past the end of an allocated buffer due to insufficient validation of user-supplied data. This information disclosure can expose sensitive memory contents and may be chained with other vulnerabilities to achieve code execution.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify PDF-XChange Editor is installedCheck for the application in Program Files (e.g., C:\Program Files\PDF-XChange\PDF-XChange Editor) or search for 'PDF-XChange Editor' in the Windows Add/Remove Programs listAffected if The application is present on the system
-
Locate the installed executableNavigate to the installation directory (typically C:\Program Files\PDF-XChange\PDF-XChange Editor) and locate the main executable (usually pdfxcview.exe or similar)Affected if The executable exists at the expected path
-
Determine the installed versionRight-click the main executable, select Properties, and check the Version tab for the File Version. Alternatively, open PDF-XChange Editor, go to Help > About to view the version numberAffected if The version displayed is below 10.4.2.390
-
Compare version to affected rangeCompare your identified version number against the affected range: versions less than 10.4.2.390 are vulnerableAffected if The installed version is a release prior to 10.4.2.390 (e.g., 10.3.x, 10.2.x, earlier)
The system is affected if PDF-XChange Editor is installed and the version is below 10.4.2.390, as the out-of-bounds read vulnerability exists in the U3D file parser of these earlier versions.
