CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local non-authenticated attacker to perform a denial of service (DoS) attack.

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)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4:


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.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
