CVE-2026-112013

libtta through 2.3 Divide by Zero via tta_decoder_init_get_info

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.

CVE-2026-112012

libtta through 2.3 Stack Out-of-Bounds Write via Zero Channel Count

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 Integer Overflow via tta_decoder_init_get_info Seek Table

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.
