# libtta: crafted TTA file overflows heap on 32-bit builds

libtta is a library for decoding TTA audio files, and through version 2.3 its decoder computes a seek table allocation from unchecked header fields that can wrap around. An attacker who supplies a crafted .tta file can cause a heap buffer overflow that crashes the application and may allow more.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

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.
