"The version of VLC media player installed on the remote host is prior to 3.0.12. It is, therefore, affected by a
heap-based buffer overflow condition. A vulnerability in EbmlTypeDispatcher::send in VideoLAN VLC media player allows
attackers to trigger a heap-based buffer overflow via a crafted .mkv file.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
