Description
Heap-based buffer overflow in the MPV_frame_start function in libavcodec/mpegvideo.c in FFmpeg before 0.9.1, when the lowres option is enabled, allows remote attackers to cause a denial of service (application crash) via a crafted H263 media file. NOTE: this vulnerability exists because of a regression error.
