Log Message:
audio_wav_parse_hdr(): avoid buffer overreads and clean up
reimplement most of this function using a new method of buffer
management to ensure that we never read beyond the provided size.
properly handle RIFF chunk lengths, instead of assuming various
offsets from most files are right.
update list of consumed documentation and fill the list of WAVE
formats from RFC 2361 (most remain not supported.)
should fix PR#57973.
tested against a large number of .wav files i have handy and with
a testsuite generator that should be incoming soon.
