Heap-based buffer overflow in ffserver.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 attackers to execute arbitrary code by leveraging failure to check chunk size.
The che_configure function in libavcodec/aacdec_template.c in FFmpeg before 3.2.1 allows remote attackers to cause a denial of service (allocation of huge memory, and being killed by the OS) via a crafted MOV file.
