1) Buffer overflow

EUVDB-ID: #VU32157

Risk: High

CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2016-2328

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

libswscale/swscale_unscaled.c in FFmpeg before 2.8.6 does not validate certain height values, which allows remote attackers to cause a denial of service (out-of-bounds array read access) or possibly have unspecified other impact via a crafted .cine file, related to the bayer_to_rgb24_wrapper and bayer_to_yv12_wrapper functions.

Mitigation

Install update from vendor's website.
