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
A NULL pointer dereference was discovered in sync_buffer in interface.c in mpglibDBL, as used in MP3Gain version 1.5.2. The vulnerability causes a segmentation fault and application crash, which leads to remote denial of service.

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

A NULL pointer dereference vulnerability exists in the sync_buffer function in interface.c in the mpglibDBL library (used by MP3Gain version 1.5.2). When processing specially crafted input, the function attempts to access memory through a NULL pointer, causing a segmentation fault and application crash, resulting in denial of service.

MitigationUpdate MP3Gain to a patched version if available. Alternatively, implement input validation and bounds checking on audio file data before passing to mpglibDBL to prevent NULL pointer dereference conditions.

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 MP3Gain version
    Run 'MP3Gain --version' or check the application properties/file metadata for version information
    Affected if The installed version is exactly 1.5.2
  2. Locate mpglibDBL library
    Search for mpglibDBL.dll or libmpglibDBL file in the MP3Gain installation directory or system libraries
    Affected if The mpglibDBL library is present and loaded by MP3Gain version 1.5.2
  3. Verify application usage
    Monitor MP3Gain process execution when processing MP3 files - the vulnerable sync_buffer function in interface.c is invoked during audio processing
    Affected if You process MP3 files using MP3Gain version 1.5.2 with the mpglibDBL library

You are affected if MP3Gain version 1.5.2 with the mpglibDBL library is used to process audio files, as the NULL pointer dereference in sync_buffer will trigger when specially crafted input is processed.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update MP3Gain to a patched version if available. Alternatively, implement input validation and bounds checking on audio file data before passing to mpglibDBL to prevent NULL pointer dereference conditions.
