An issue was discovered in zlib_decompress_extra in modules/demux/mkv/util.cpp in VideoLAN VLC media player 3.x through 3.0.7. The Matroska demuxer, while parsing a malformed MKV file type, has a double free.

Weakness

The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations.
