Unintentional integer overflow

[CoSunshine]

Dear developer:
There is a potential integer overflow as indicated by the following function:
https://github.com/allyourcodebase/ffmpeg/blob/main/libavcodec/pcm-dvdenc.c#L119

FFmpeg already patched this using the following commit. FFmpeg/FFmpeg@160b81c

Do we need to update this vulnerability?

Similar for this one:
https://github.com/allyourcodebase/ffmpeg/blob/main/libswscale/swscale.c#L190
also suffer from integer overflow and the library already patched this one
FFmpeg/FFmpeg@5f5421e

https://github.com/allyourcodebase/ffmpeg/blob/main/libavcodec/jpegxl_parser.c#L1469 suffers from integer overflow for some malformed files and already be patched by FFmpeg/FFmpeg@0225fe8

https://github.com/allyourcodebase/ffmpeg/blob/main/libavcodec/osq.c#L227 suffers from undefined overflows in do_decode() and be patched by undefined overflows in do_decode() and dst[n] *= 256;FFmpeg/FFmpeg@ed34b0c

It's all your one-sided talk; has the author already abandoned this project?
