stb_vorbis through 1.22 contains a heap buffer overflow in start_decoder() where the codebook multiplicands allocation size is truncated from size_t to int. Attackers can craft a malicious Ogg Vorbis file with large entries and dimensions values to trigger out-of-bounds writes, causing process crashes or heap corruption.
