AI-suggested
A fix is available as indicated by the referenced commits (1df46ae), though no official patched version number is provided in this data. Users should update to a version including these commits once available. Until then, avoid processing untrusted WAV files with vulnerable versions of miniaudio.
Description
miniaudio version 0.11.25 and earlier (fixed in commits 1df46ae and 1df46ae) contain a heap out-of-bounds read vulnerability in the WAV BEXT metadata parser that allows attackers to trigger memory access violations by processing crafted WAV files. Attackers can exploit improper null-termination handling in the coding history field to cause out-of-bounds reads past the allocated metadata pool, resulting in application crashes or denial of service.
