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
hwpapp.dll in Hangul Word Processor allows remote attackers to execute arbitrary code via a crafted heap spray, and by leveraging a "type confusion" via an HWPX file containing a crafted para text tag.

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 confidence

A type confusion vulnerability in hwpapp.dll within Hangul Word Processor allows remote code execution through specially crafted HWPX files. Attackers exploit this by using heap spray techniques combined with a malformed para text tag in the HWPX XML document format.

MitigationUpdate Hangul Word Processor to the latest patched version. Avoid opening untrusted HWPX files from unknown sources until the patch is applied.

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. Confirm Hangul Word Processor installation
    Check for Hangul Word Processor in installed programs (Add/Remove Programs on Windows) or look for executable (Hangul.exe) in program directories
    Affected if Hangul Word Processor version 2014 is installed
  2. Verify exact version number
    Right-click Hangul.exe, select Properties, and check the File Version under the Details tab. Alternatively, open Hangul and go to Help > About Hangul to display the version
    Affected if Version displayed is exactly 2014 (any subversion)
  3. Check HWPX file handling capability
    Attempt to open or associate an HWPX file with Hangul Word Processor. Verify that .hwpx extension is recognized and handled by the application
    Affected if HWPX files can be opened in Hangul 2014 (default behavior)
  4. Locate vulnerable DLL
    Search for hwpapp.dll in the Hangul program installation directory (typically C:\Program Files\Hancom\Hangul\ or similar path)
    Affected if hwpapp.dll exists in the Hangul 2014 installation folder

A user is affected if Hangul Word Processor version 2014 is installed and the application can open HWPX files, since the vulnerability resides in hwpapp.dll when processing malformed para text tags in HWPX documents.
