CVE-2013-7012: Buffer Overflow

First published: Mon Dec 09 2013(Updated: )

The get_siz function in libavcodec/jpeg2000dec.c in FFmpeg before 2.1 does not prevent attempts to use non-zero image offsets, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted JPEG2000 data.
