What it is

SoX through 14.4.2 contains a heap out-of-bounds write vulnerability in lsx_ms_adpcm_block_expand_i() in src/adpcm.c, triggered by an odd samplesPerBlock value in the WAV fmt chunk. Attackers can supply a crafted MS ADPCM WAV file to sox or any libsox consumer to write a partially controlled 16-bit sample past the heap buffer allocated by wav_ms_adpcm_fmt().
