Description

This module exploits a use after free vulnerability in
VideoLAN VLC = MKV files and affects both 32 bits and 64 bits.

In order to exploit this, this module will generate two files:
The first .mkv file contains the main vulnerability and heap spray,
the second .mkv file is required in order to take the vulnerable code
path and should be placed under the same directory as the .mkv file.

This module has been tested against VLC v2.2.8. Tested with payloads
windows/exec, windows/x64/exec, windows/shell/reverse_tcp,
windows/x64/shell/reverse_tcp. Meterpreter payloads if used can
cause the application to crash instead.
