## Overview

Schroedinger libschroedinger through 1.0.11 contains an out-of-bounds read vulnerability that allows attackers to read past a static quantiser table by supplying unvalidated wavelet filter index or transform depth values. Attackers can deliver a crafted low-delay Dirac stream with a wavelet filter index of 7 or more or transform depth of 5 or 6 to crash decoding applications.

## Affected

- `schroedinger <= 1.0.11`

## Remediation
