The zlib_refill function in libavformat/swfdec.c in FFmpeg before 3.1.3 allows remote attackers to cause an infinite loop denial of service via a crafted SWF file.


2) Heap-based buffer overflow (CVE-ID: CVE-2016-6920)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in Heap-based buffer overflow in the decode_block function in libavcodec/exr.c in FFmpeg before 3.1.3. A remote attacker can use vectors involving tile positions. to trigger a heap-based buffer overflow and execute arbitrary code on the target system.
