CVE-2015-1872: Buffer Overflow
First published: Sun Jul 26 2015(Updated: )
The ff_mjpeg_decode_sof function in libavcodec/mjpegdec.c in FFmpeg before 2.5.4 does not validate the number of components in a JPEG-LS Start Of Frame segment, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted Motion JPEG data.
