Short explanation

SoX through 14.4.2 contains a heap out-of-bounds write vulnerability in lsx_ms_adpcm_block_expand_i() triggered by an odd samplesPerBlock value in the WAV fmt chunk.

Why does it matter?

It allows attackers to target applications using a crafted audio file and achieve partial data control past the heap buffer.

What should be done?

Monitor official channels for patch details.
Follow vendor advisory guidance.
Avoid processing untrusted audio files.

Show the technical text from the sources

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().
