1) Buffer overflow (CVE-ID: CVE-2015-8662)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
The ff_dwt_decode function in libavcodec/jpeg2000dwt.c in FFmpeg before 2.8.4 does not validate the number of decomposition levels before proceeding with Discrete Wavelet Transform decoding, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted JPEG 2000 data.
