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
Integer overflow in the in_nsv plugin in Winamp before 5.6 allows remote attackers to have an unspecified impact via vectors related to improper allocation of memory for NSV metadata, a different vulnerability than CVE-2010-2586.

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 vulnerability in Winamp's in_nsv plugin (versions before 5.6) allows remote attackers to cause improper memory allocation for NSV metadata, potentially leading to arbitrary code execution. The flaw exists in how the plugin processes NSV file metadata without sufficient bounds checking on size values used in memory allocation calculations.

MitigationUpgrade Winamp to version 5.6 or later. If upgrading is not possible, disable or remove the in_nsv plugin to eliminate the attack surface. Implement network-level filtering to block untrusted NSV files from reaching the vulnerable client.

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
    Check for Winamp installation by looking for the Winamp directory, typically at C:\Program Files\Winamp\ or C:\Program Files (x86)\Winamp\, or by searching for winamp.exe on the system.
    Affected if Winamp is installed on the system.
  2. Identify Winamp version
    Right-click winamp.exe, select Properties, and check the Version tab for the product version. Alternatively, run Winamp, click Help > About Winamp to display the version number.
    Affected if The displayed 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, or 2.95.
  3. Locate the in_nsv plugin file
    Navigate to the Winamp plugins folder (usually C:\Program Files\Winamp\Plugins\ or C:\Program Files (x86)\Winamp\Plugins\) and search for in_nsv.dll.
    Affected if The in_nsv.dll file exists in the plugins directory, indicating the vulnerable plugin is present.
  4. Verify plugin is enabled
    Open Winamp, go to Options > Preferences > Plugins > Input and look for "Nullsoft NSV (in_nsv) Decoder" in the list of available input plugins.
    Affected if The in_nsv plugin appears in the enabled input plugins list.

If Winamp version 5.581 or lower is installed and the in_nsv plugin (in_nsv.dll) is present and enabled, the system is affected by this vulnerability.

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

Upgrade Winamp to version 5.6 or later. If upgrading is not possible, disable or remove the in_nsv plugin to eliminate the attack surface. Implement network-level filtering to block untrusted NSV files from reaching the vulnerable client.

Recommended fix High confidence

Winamp 5.6 or later

  1. Download Winamp version 5.6 or later from the official Winamp website
  2. Install the new version, ensuring to back up any existing playlist or configuration files first
  3. Verify the installed version by checking Help > About Winamp to confirm version 5.6 or higher is running
