DescriptionCVE.org
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.
AnalysisAI
Keras versions up to 3.13.0 is affected by allocation of resources without limits or throttling (CVSS 7.5).
