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 · uneditedA Buffer Overflow in VLC Media Player < 3.0.7 causes a crash which can possibly be further developed into a remote code execution exploit.
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 confidenceBuffer overflow vulnerability in VLC Media Player versions prior to 3.0.7. The overflow occurs during media parsing/processing and causes a denial of service (crash), with potential for further development into remote code execution.

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 checksWork through these to decide whether this CVE applies to you.
-
Check VLC version via command lineOpen a terminal or command prompt and run 'vlc --version' or 'vlc -V' to display the installed VLC Media Player version numberAffected if The displayed version is any release prior to 3.0.7 (for example 3.0.6, 3.0.5, 3.0.4, etc.)
-
Check VLC version on Windows via file propertiesNavigate to the VLC installation directory (typically C:\Program Files\VideoLAN\VLC or C:\Program Files (x86)\VideoLAN\VLC), right-click on vlc.exe, select Properties, and view the Details tab showing the File VersionAffected if The file version shown is lower than 3.0.7.0
-
Check VLC version on Linux via package managerFor Debian/Ubuntu systems, run 'dpkg -l | grep vlc' or 'apt-cache policy vlc'. For Red Hat/CentOS systems, run 'rpm -q vlc'. For Arch Linux, run 'pacman -Q vlc'Affected if The packaged version number returned is less than 3.0.7
-
Check VLC version on macOSOpen the Applications folder, right-click on VLC.app, select Get Info, and view the Version number under the General tabAffected if The version shown is any release before 3.0.7
A system is affected if the installed VLC Media Player version is any release prior to version 3.0.7, as the buffer overflow vulnerability exists in all earlier versions.
