Ubuntu priority

Low

Why this priority?

Heap-based buffer overflow in the ws_snd_decode_frame function in libavcodec/ws-snd1.c in FFmpeg 0.9.1 allows remote attackers to cause a denial of service (application crash) via a crafted media file, related to an incorrect calculation, aka "wrong samples count."
