CVE-2022-41153
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 · uneditedThis 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. Crafted data in a U3D file can trigger 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-18343.
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 confidencePDF-XChange Editor contains an out-of-bounds read vulnerability in its U3D file parser. Crafted U3D data triggers a read past the end of an allocated buffer, allowing disclosure of sensitive information. This vulnerability can be chained with other flaws to achieve arbitrary 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.
-
Identify installed PDF-XChange Editor versionOpen Windows PowerShell and run Get-WmiObject Win32_Product | Select-Object Name, Version, Vendor to list installed PDF-XChange products and their version numbersAffected if The installed version is below 9.5.366.0
-
Verify U3D file parsing capabilityCheck if the application has processed any PDF files containing U3D (Universal 3D) content by examining recent documents or looking for 3D annotation support in the editorAffected if U3D parsing is available and PDFs with 3D content have been opened
-
Inspect application crash or error logsReview PDF-XChange Editor logs or Windows Event Viewer for any recent errors related to U3D parsing or out-of-bounds memory accessAffected if Errors referencing U3D parser or memory read failures are logged
Environment is affected if PDF-XChange Editor version is below 9.5.366.0 and the software is used to open or process PDF files containing U3D 3D content.
