[FFmpeg-cvslog] avformat/lafdec: Check for EOF in header reading
ffmpeg | branch: master | Michael Niedermayer | Sat
Nov 12 18:14:19 2022 +0100| [b92260f70a4ac194d1cc09c40b92766d38c7c783] |

avformat/lafdec: Check for EOF in header reading
Fixes: OOM testcase
Fixes:
51527/clusterfuzz-testcase-minimized-ffmpeg_dem_LAF_fuzzer-5453663505612800
OOM can still happen after this as an arbitrary sized block is allocated and
read
this would require a redesign or some limit on the sample rate.
