## Description

The smka\_decode\_frame function in libavcodec/smacker.c in FFmpeg before
2.6.5, 2.7.x before 2.7.3, and 2.8.x through 2.8.2 does not verify that the
data size is consistent with the number of channels, which allows remote
attackers to cause a denial of service (out-of-bounds array access) or
possibly have unspecified other impact via crafted Smacker data.
