In VideoLAN VLC media player through 2.2.8, there is a type conversion vulnerability in modules/demux/mp4/libmp4.c in the MP4 demux module leading to a invalid free, because the type of a box may be changed between a read operation and a free operation.
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
