## Overview

FFmpeg through 9.0.2 contains an uninitialized memory disclosure vulnerability in raw_decode() in libavcodec/rawdec.c that fails to verify packet stride covers a full row for 1 to 8 bits per pixel video. Attackers can supply crafted AVI, MOV or NUT files with truncated low bit depth rawvideo packets to leak uninitialized heap memory through decoded frame output.

## Affected

- `FFmpeg <= 9.0.2`
