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
DaviewIndy 8.98.4 and earlier version contain Heap-based overflow vulnerability, triggered when the user opens a malformed specific file that is mishandled by Daview.exe. Attackers could exploit this and arbitrary code execution.

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

DaviewIndy 8.98.4 and earlier versions contain a heap-based buffer overflow vulnerability in Daview.exe when parsing malformed files. The vulnerability occurs during file handling of a specific file type, allowing attackers to achieve arbitrary code execution via a specially crafted malicious file.

MitigationUsers should avoid opening untrusted or unverified files in DaviewIndy until a vendor patch is available. Organizations should consider deploying additional endpoint protection capable of detecting malicious file payloads.

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. Identify DaviewIndy installation version
    Locate the DaviewIndy installation directory (commonly in Program Files) and check the file properties of Daview.exe, or use the application's About/Help menu to view the version number
    Affected if The displayed version is 8.98.4 or any earlier version (e.g., 8.98.3, 8.98.2, etc.)
  2. Confirm Daview.exe is present
    Search for Daview.exe in the installation folder - the vulnerability exists in this executable during file parsing operations
    Affected if Daview.exe exists on the system and is used for opening files
  3. Determine if file parsing is actively used
    Review whether users or automated processes open files using DaviewIndy - the vulnerability triggers when Daview.exe parses malformed files
    Affected if DaviewIndy is used to open or process files, particularly from untrusted sources

A system is affected if DaviewIndy version 8.98.4 or earlier is installed and Daview.exe is used to parse files, since the heap overflow occurs during malformed file handling in this component.
