MP4Box is a component of GPAC-2.0.0, which is a widely-used third-party package on RPM Fusion. When MP4Box tries to parse a MP4 file, it calls the function `diST_box_read()` to read from video. In this function, it allocates a buffer `str` with fixed length. However, content read from `bs` is controllable by user, so is the length, which causes a buffer overflow.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
The product reads data past the end, or before the beginning, of the intended buffer.
