CVE-2015-6821

Published: 6 September 2015

The ff_mpv_common_init function in libavcodec/mpegvideo.c in FFmpeg before 2.7.2 does not properly maintain the encoding context, which allows remote attackers to cause a denial of service (invalid pointer access) or possibly have unspecified other impact via crafted MPEG data.
