Name of the Vulnerable Software and Affected Versions TensorFlow versions prior to 2.6.0 TensorFlow versions 2.5.1 and earlier TensorFlow versions 2.4.3 and earlier TensorFlow versions 2.3.4 and earlier

Description An attacker can trigger a crash via a floating point exception in tf.raw ops.ResourceGather. The implementation computes the value of batch size and then divides by it without checking that this value is not 0. This can be exploited by creating a tensor with a specific shape and dtype, and then using tf.raw ops.ResourceGather with a batch dims value of 1 and validate indices set to False.

Recommendations For versions prior to 2.6.0, update to TensorFlow 2.6.0 or later. For versions 2.5.1 and earlier, update to TensorFlow 2.5.1 or later. For versions 2.4.3 and earlier, update to TensorFlow 2.4.3 or later. For versions 2.3.4 and earlier, update to TensorFlow 2.3.4 or later. As a temporary workaround, consider avoiding the use of tf.raw ops.ResourceGather with a batch dims value of 1 and validate indices set to False until a patch is available.
