Description

SDL_mixer 3.1.2 through 3.2.4 contains a stack-based buffer overflow vulnerability in FetchXLaw() of src/decoder_wav.c when decoding A-law or mu-law WAV files. Attackers can supply a crafted WAV file whose doubly-offset float expansion overwrites about 1 KB of adjacent stack memory, causing crashes or potentially code execution.
