libtta through 2.3 contains a divide-by-zero vulnerability in tta_decoder_init_get_info() that allows attackers to crash applications by supplying an unvalidated zero sample rate. Attackers can craft a .tta file with a recomputed header CRC32 that triggers SIGFPE, crashing applications including the bundled tta console tool.
