calling memcpy() with a wrong size, leading to a denial of service
(application crash) or possibly code execution.

It was discovered that plugins\codec\libflac_plugin.so in VideoLAN VLC
media player before 2.2.7 allows remote attackers to cause a heap
corruption and application crash leading to denial of service or
possibly execution of arbitrary code via a crafted FLAC file.

Impact
======

A remote attacker is able to execute arbitrary code on the host by
providing a maliciously-crafted media file to VLC.
