## Overview

Allocation of Resources Without Limits or Throttling in the HDF5 weight loading component in Google Keras 3.0.0 through 3.13.0 on all platforms allows a remote attacker to cause a Denial of Service (DoS) through memory exhaustion and a crash of the Python interpreter via a crafted .keras archive containing a valid model.weights.h5 file whose dataset declares an extremely large shape.

## Affected

- `keras >= 3.0.0, <= 3.13.0`

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
