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
An out-of-bounds read vulnerability has been discovered in Monkey's Audio 11.31, specifically in the CAPECharacterHelper::GetUTF16FromUTF8 function. The issue arises from improper handling of the length of the input UTF-8 string, causing the function to read past the memory boundary. This vulnerability may result in a crash or expose sensitive data.

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

An out-of-bounds read vulnerability exists in Monkey's Audio 11.31 within the CAPECharacterHelper::GetUTF16FromUTF8 function. The function improperly handles the length of input UTF-8 strings during UTF-8 to UTF-16 conversion, causing reads to extend past the allocated buffer boundary, potentially leading to crash or information disclosure.

MitigationUpgrade to a patched version of Monkey's Audio when available. Until then, exercise caution when processing untrusted audio files and consider sandboxing or isolating the decoder from sensitive data.

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 Monkey's Audio installation
    Search for Monkey's Audio executable (APE.exe, MAC.exe, or monkeyaudio.exe) in common program directories or via system search, then right-click the executable and select Properties to view the File Version
    Affected if Monkey's Audio version 11.31 is installed
  2. Confirm installed version number
    In the File Properties window, locate the Version tab and read the Product Version field; alternatively run the executable with a version flag if supported (e.g., --version)
    Affected if The reported version is exactly 11.31 or falls within the 11.x range prior to any patched release
  3. Verify UTF-8 metadata processing is active
    Inspect any active processes or applications that use Monkey's Audio for decoding; check if audio files containing UTF-8 encoded metadata (artist, album, title tags) are being processed
    Affected if The application decodes or parses audio files with UTF-8 character data using the affected conversion routine
  4. Check for crash or异常 behavior logs
    Review system event logs, application logs, or any debug output for crashes, access violations, or unexpected terminations when processing Monkey's Audio files
    Affected if Crashes or access violations occur specifically when loading or playing .ape, .mac, or other Monkey's Audio format files containing non-ASCII metadata

A user is affected if Monkey's Audio version 11.31 is installed and is being used to process audio files with UTF-8 encoded metadata, as the CAPECharacterHelper::GetUTF16FromUTF8 function will attempt out-of-bounds reads during conversion.
