Name of the Vulnerable Software and Affected Versions TensorFlow versions prior to 2.7.0 TensorFlow versions 2.6.1 and earlier TensorFlow versions 2.5.2 and earlier TensorFlow versions 2.4.4 and earlier

Description The Keras pooling layers in TensorFlow can trigger a segfault if the size of the pool is 0 or if a dimension is negative. This issue arises due to TensorFlow's implementation of pooling operations, where the values in the sliding window are not checked to be strictly positive.

Recommendations For versions prior to 2.7.0, update to TensorFlow 2.7.0 or later. For versions 2.6.1 and earlier, update to TensorFlow 2.6.1 or later. For versions 2.5.2 and earlier, update to TensorFlow 2.5.2 or later. For versions 2.4.4 and earlier, update to TensorFlow 2.4.4 or later. As a temporary workaround, consider avoiding the use of Keras pooling layers with a pool size of 0 or negative dimensions until a patch is available.
