CVE-2013-7018: Buffer Overflow

First published: Mon Dec 09 2013(Updated: )

libavcodec/jpeg2000dec.c in FFmpeg before 2.1 does not ensure the use of valid code-block dimension values, 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.
