A vulnerability in the MKV demuxer plugin (libmkv_plugin) of VLC media player versions 1.1.6.1 and earlier allows remote attackers to cause a denial of service (crash) and potentially execute arbitrary code via a specially crafted MKV (Matroska or WebM) file. The flaw is due to insufficient input validation and memory corruption related to class mismatching and the MKV_IS_ID macro in demux/mkv/mkv.hpp. Exploitation requires user interaction to open the malicious file.

This repository contains a single Metasploit exploit module targeting a memory corruption vulnerability (CVE-2011-0531) in VideoLAN VLC media player versions prior to 1.1.7, specifically tested on VLC 1.1.6 running on Windows XP SP3. The exploit works by generating a specially crafted MKV or WebM file (default name: msf.webm) that, when opened in a vulnerable VLC instance, triggers a heap corruption via malformed EBML/segment data. The exploit uses a heap spray and a ROP chain to bypass DEP/NX protections and execute a customizable Metasploit payload, typically resulting in arbitrary code execution with user privileges. The module is operational and allows the attacker to specify the payload, making it flexible for various post-exploitation scenarios. The attack vector is local, requiring the victim to open the malicious file. No network endpoints are involved; the only fingerprintable endpoint is the generated file itself.
