The tak_decode_frame function in libavcodec/takdec.c in FFmpeg before 2.1.4 does not properly validate a certain bits-per-sample value, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted TAK (aka Tom's lossless Audio Kompressor) data.
Improper Input Validation The product receives input or data, but it does
not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly.
