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
avcodec 2.2.x, as used in VideoLAN VLC media player 2.2.7-x before 2017-06-29, allows out-of-bounds heap memory write due to calling memcpy() with a wrong size, leading to a denial of service (application crash) or possibly code execution.

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

A heap-based buffer overflow vulnerability exists in avcodec 2.2.x where memcpy() is called with an incorrect size parameter, causing out-of-bounds memory writes. This memory corruption in the VLC media player 2.2.7-x can lead to denial of service via application crash or potentially allow remote code execution.

MitigationUpgrade VLC media player to version 2.2.7 or later (post-2017-06-29) which contains the patched avcodec library, or update avcodec to a version that corrects the memcpy size validation.

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 VLC installation path and binary
    Run 'where vlc' on Windows or 'which vlc' on Linux/macOS to locate the VLC executable. Alternatively, check common installation directories.
    Affected if VLC executable is found on the system
  2. Determine installed VLC version
    Run 'vlc --version' or right-click the VLC executable, select Properties, and check the Details tab for the File Version.
    Affected if The version displayed is any of: 2.2.0, 2.2.1, 2.2.2, 2.2.3, 2.2.4, 2.2.5, 2.2.5.1, 2.2.6, or 2.2.7
  3. Confirm avcodec library version in use
    On Windows, check the 'plugins' folder inside the VLC installation directory for avcodec DLL version. On Linux, run 'dpkg -l | grep libavcodec' or check /usr/lib/x86_64-linux-gnu/ for libavcodec.so versions.
    Affected if The avcodec library version is 2.2.x matching the affected VLC versions (the vulnerability is in the bundled avcodec within these VLC releases)

If VLC Media Player version 2.2.0 through 2.2.7 is installed with its bundled avcodec 2.2.x library, the system is vulnerable to heap-based buffer overflow via malicious media file processing.

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

Upgrade VLC media player to version 2.2.7 or later (post-2017-06-29) which contains the patched avcodec library, or update avcodec to a version that corrects the memcpy size validation.

Recommended fix High confidence

VLC Media Player 2.2.7 or later (or current stable release)

  1. Check the current VLC Media Player version by opening VLC and navigating to Help > About VLC, or by running 'vlc --version' from command line
  2. Visit the official VideoLAN VLC download page at www.videolan.org
  3. Download the latest stable VLC Media Player version (2.2.7 or later, or the current stable release)
  4. Uninstall the existing vulnerable VLC version (2.2.x series) from the system
  5. Install the downloaded fixed version of VLC Media Player
Caveat Minor - VLC 2.2.x to 2.2.7 is a patch update within the same major.minor branch; some codec support differences may exist but core functionality is preserved
