The read_gab2_sub function in libavformat/avidec.c in FFmpeg before 3.1.4 allows remote attackers to cause a denial of service (NULL pointer used) via a crafted AVI file.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
