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
Buffer overflow in the in_mod plugin in Winamp before 5.6 allows remote attackers to have an unspecified impact via vectors related to the comment box.

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

Buffer overflow vulnerability in Winamp's in_mod plugin (handles MOD audio files) before version 5.6. The flaw exists in the comment box handling functionality, allowing remote attackers to overflow a buffer and potentially execute arbitrary code via specially crafted MOD file metadata.

MitigationUpdate Winamp to version 5.6 or later to obtain the patched in_mod plugin. If updating is not feasible, avoid opening untrusted MOD files from unknown sources.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 Winamp installation
    Locate Winamp installation directory (commonly C:\Program Files\Winamp\ or C:\Program Files (x86)\Winamp\) and verify winamp.exe exists
    Affected if Winamp is not installed on the system
  2. Identify installed Winamp version
    Right-click winamp.exe, select Properties, then look at the Details tab for Product Version, or run: wmic datafile where "name='C:\\Program Files\\Winamp\\winamp.exe'" get Version
    Affected if Version is 5.581 or lower, or matches any of these specific versions: 0.20a, 0.92, 1.006, 1.90, 2.0, 2.6, 2.9, 2.10, 2.91, 2.92, 2.95
  3. Verify in_mod plugin presence
    Check for in_mod.dll in the Winamp plugins folder (typically C:\Program Files\Winamp\Plugins\)
    Affected if in_mod.dll exists and is loaded by Winamp for MOD file playback
  4. Test MOD file handling capability
    Open Winamp, go to Options > Preferences > Plugins > Input, confirm in_mod plugin is listed and enabled
    Affected if in_mod plugin is enabled and available for handling MOD audio files

A user is affected if Winamp version is 5.581 or lower (or matches one of the listed specific versions), the in_mod plugin is present, and the user opens or previews specially crafted MOD files with malicious metadata.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Upgrade available Upgrade to a release after 5.581
Interim mitigation

Update Winamp to version 5.6 or later to obtain the patched in_mod plugin. If updating is not feasible, avoid opening untrusted MOD files from unknown sources.

Recommended fix High confidence

Winamp 5.6 or later

  1. Backup your Winamp settings, skins, and playlists if desired
  2. Download Winamp 5.6 or later from the official Winamp website (winamp.com)
  3. Run the installer and follow the prompts to upgrade, allowing it to overwrite the existing installation
  4. Launch Winamp and verify the version by going to Options > Preferences > General Preferences - the version number should display as 5.6 or higher
