The mov_read_dref function in libavformat/mov.c in Libav before 11.7 and FFmpeg before 0.11 allows remote attackers to cause a denial of service (memory corruption) or execute arbitrary code via the entries value in a dref box in an MP4 file.
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.
