| Package | Affected versions | Patched versions |
|---|---|---|
| ffmpeg | ≤ 2.5.1 |
The vmd_decode function in libavcodec/vmdvideo.c in FFmpeg before 2.5.2 does not validate the relationship between a certain length value and the frame width, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted Sierra VMD video data.
