Heap-based buffer overflow in libavformat/http.c in FFmpeg before 2.8.10, 3.0.x before 3.0.5, 3.1.x before 3.1.6, and 3.2.x before 3.2.2 allows remote web servers to execute arbitrary code via a negative chunk size in an HTTP response.
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.
