The MP4_ReadBox_String function in modules/demux/mp4/libmp4.c in VideoLAN VLC media player before 2.1.6 allows remote attackers to trigger an unintended zero-size malloc and conduct buffer overflow attacks, and consequently execute arbitrary code, via a box size of 7.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
