Description

The (1) av_image_fill_pointers, (2) vp5_parse_coeff, and (3) vp6_parse_coeff functions in FFmpeg 0.5.x before 0.5.7, 0.6.x before 0.6.4, 0.7.x before 0.7.9, and 0.8.x before 0.8.8; and in Libav 0.5.x before 0.5.6, 0.6.x before 0.6.4, and 0.7.x before 0.7.3 allow remote attackers to cause a denial of service (out-of-bounds read) via a crafted VP5 or VP6 stream.
