CVE-2016-2327: Buffer Overflow
First published: Fri Feb 12 2016(Updated: )
libavcodec/pngenc.c in FFmpeg before 2.8.5 uses incorrect line sizes in certain row calculations, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via a crafted .avi file, related to the apng_encode_frame and encode_apng functions.
