When `axfer`'s WAVE container parser processes a crafted WAVE file missing the `fmt` chunk, `samples_per_frame` and `frames_per_second` remain zero, causing a division-by-zero in `wave_parser_pre_process()`. ### Impact - Denial-of-service via process crash - Any user processing untrusted WAVE files with axfer is affected ### Reproduction All materials are available in my research repository: https://github.com/eglonnnn/opensource-fuzz-vulnerability-research/tree/main/FPE%20in%20alsa-utils%20axfer%20wave_parser_pre_process Issue URL : https://github.com/alsa-project/alsa-utils/issues/332 Repository URL: https://github.com/alsa-project/alsa-utils
