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 · unedited
PDF-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 object. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process. Was ZDI-CAN-25957.

dbcve analysis · high confidence

An out-of-bounds read vulnerability exists in PDF-XChange Editor's U3D file parser due to insufficient validation of user-supplied data during parsing. The lack of bounds checking allows reading past the end of an allocated object, leading to information disclosure. While this flaw alone enables disclosure, it can be chained with other vulnerabilities to achieve arbitrary code execution in the current process context.

MitigationApply vendor-supplied patches for PDF-XChange Editor immediately. Until patched, instruct users to avoid opening untrusted PDF files or visiting malicious pages that may deliver crafted U3D content.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify PDF-XChange Editor is installed
    Check for the presence of PDF-XChange Editor in the system by searching for the executable file (PDFXEdit.exe) in typical installation locations such as C:\Program Files\PDF-XChange\ or by checking Add/Remove Programs in Windows Control Panel
    Affected if PDF-XChange Editor is found on the system
  2. Determine the installed version number
    Right-click on PDFXEdit.exe, select Properties, then view the Details tab to find the File Version, or run the application and navigate to Help > About to display the version information
    Affected if The version displayed is lower than 10.5.0.393 (for example, 10.4.x, 10.3.x, or earlier)
  3. Confirm U3D parsing capability is present
    Attempt to open a PDF file containing U3D 3D content or check if the application has U3D-related DLLs (such as U3D.dll or similar) present in the installation directory
    Affected if U3D parsing modules are present in the application and the version is below 10.5.0.393
  4. Check for recent PDF files with U3D content
    Search the file system for PDF files that may contain embedded U3D objects, typically identified by searching for files with .pdf extension and examining them with a hex editor or PDF parsing tool for U3D stream objects
    Affected if The system contains PDF files with embedded U3D content and the installed PDF-XChange Editor version is below 10.5.0.393

The system is affected if PDF-XChange Editor is installed with a version lower than 10.5.0.393 and the application is used to open PDF files containing U3D content.
