VLC Media Player MKV Demuxer Vulnerability

Date Disclosed:

Date Patched:


Affected Software:
VLC Media Player 1.x

VLC Media Player contains a vulnerability in the MKV demuxer when handling maliciously crafted MKV files. An attacker may send a target a specially crafted MKV file, which causes an input validation error within the demuxer. Successful exploitation could allow execution of arbitrary code.


Code Execution:

Arbitrary code execution under the current user's context.
This client-side vulnerability could allow an attacker to gain the ability to execute remote arbitrary code with the same permissions as the user that is currently logged in. If the user is an administrator, the attacker could install malicious software and further compromise the system.

Do not open '.mkv' files, or manually remove the MKV demuxer plugin (libmkv_plugin.*) from the plugin installation directory.
