Synopsis :

The remote FreeBSD host is missing one or more security-related
updates.

Description :

NVD reports :

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.

The ff_get_buffer function in libavcodec/utils.c in FFmpeg before
2.8.4 preserves width and height values after a failure, which allows
remote attackers to cause a denial of service (out-of-bounds array
access) or possibly have unspecified other impact via a crafted .mov
file.
