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
Multiple integer overflows in the in_midi plugin in Winamp before 5.6 allow remote attackers to execute arbitrary code via a crafted MIDI file that triggers a buffer overflow.

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

Integer overflow vulnerabilities in the in_midi plugin's MIDI file parsing code in Winamp versions before 5.6 allow specially crafted MIDI files to trigger buffer overflows, enabling remote arbitrary code execution.

MitigationUpgrade Winamp to version 5.6 or later; avoid opening MIDI files from untrusted sources until the upgrade is applied.

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. Verify Winamp is installed
    Check for Winamp installation directory (commonly at C:\Program Files\Winamp or C:\Program Files (x86)\Winamp) and verify winamp.exe exists
    Affected if Winamp is installed and the directory exists
  2. Identify installed Winamp version
    Right-click winamp.exe, select Properties, then view the Version tab; or run 'winamp.exe /?' or check Add/Remove Programs for the version number
    Affected if Version is 5.581 or lower, or matches any of these: 0.20a, 0.92, 1.006, 1.90, 2.0, 2.6, 2.9, 2.10, 2.91, 2.92, 2.95
  3. Confirm in_midi plugin is present
    Navigate to the Winamp plugins folder (typically Winamp\Plugins\) and verify in_midi.dll exists
    Affected if in_midi.dll is present in the plugins directory and the Winamp version is vulnerable
  4. Check if MIDI playback is enabled
    Open Winamp, go to Options > Preferences > Plug-ins > Input, and verify Nullsoft MIDI Decoder (in_midi) is listed as an available input plugin
    Affected if The in_midi input plugin is enabled or available in Winamp

User is affected if Winamp is installed with version 5.581 or lower (or any of the specific older versions listed) and the in_midi plugin is present and enabled for MIDI file handling.

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

Upgrade Winamp to version 5.6 or later; avoid opening MIDI files from untrusted sources until the upgrade is applied.

Recommended fix High confidence

Winamp 5.6 or later

  1. 1. Backup any important Winamp playlist files (.m3u, .m3u8) and skin configurations if desired
  2. 2. Download Winamp 5.6 or a later stable version from the official Winamp website (winamp.com) or a trusted mirror
  3. 3. Run the Winamp installer and follow the prompts to install the new version
  4. 4. Verify the installation completed successfully by checking the version number in Winamp's 'About' section
Caveat Standard minor version upgrade - should preserve playlists and most settings; older skins may need reconfiguration
