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
XnView MP 0.93.1 on Windows allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted file, related to ntdll!RtlReAllocateHeap.

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 · moderate confidence

XnView MP 0.93.1 on Windows contains a heap corruption vulnerability triggered by specially crafted image files. The vulnerability resides in how the application handles file parsing, leading to a flaw in the Windows ntdll!RtlReAllocateHeap function. Opening a malicious file can cause application crash (denial of service) and potentially enable arbitrary code execution.

MitigationDo not open untrusted or unverified image files in XnView MP until an official patch is released. Consider updating to a newer version of XnView MP if available, or use an alternative image viewer for untrusted 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 XnView MP is installed
    Check for XnView MP installation directory (commonly C:\Program Files\XnView MP or C:\Program Files (x86)\XnView MP) or search for xnview.exe in Program Files
    Affected if XnView MP executable exists on the system
  2. Determine installed version
    Right-click xnview.exe, select Properties, then check the Details tab for Product Version, or launch XnView MP and go to Help > About to display the version number
    Affected if Version displayed is exactly 0.93.1
  3. Confirm file parsing functionality is available
    Verify the application can open and parse image files (try opening any image file via File > Open or drag-and-drop)
    Affected if XnView MP can open image files and the version is 0.93.1

You are affected only if XnView MP version 0.93.1 is installed AND you use it to open image files from untrusted sources.
