The ff_draw_pc_font function in libavcodec/cga_data.c in FFmpeg before 3.1.4 allows remote attackers to cause a denial of service (buffer overflow) via a crafted AVI 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.
