True Audio Libtta vulnerabilities

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.

libtta through 2.3 contains a stack out-of-bounds read and write vulnerability in tta_decoder_process_stream() and tta_decoder_process_frame() because header checks never reject a zero channel count. Attackers can supply a crafted .tta file declaring zero channels so decorrelation accesses cache[-1] with stream-derived values, corrupting stack memory in decoding applications.

libtta through 2.3 contains an integer overflow vulnerability in tta_decoder_init_get_info() that allows attackers to cause a heap buffer overflow on 32-bit builds via unvalidated header fields. Attackers can supply a crafted .tta file with a sample rate of 1 and large samples value, wrapping the seek table allocation and crashing applications.
