libsndfile 1.2.2 contains a misaligned memory access issue in psf_binheader_readf() while parsing WAV fmt chunks. A specially crafted WAV file can cause the function to cast an unaligned destination address to unsigned int * and perform a 4-byte store. This results in undefined behavior leading to denial of service.
