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 The implementation of tf.raw ops.SparseDenseCwiseDiv is vulnerable to a division by 0 error. The implementation uses a common class for all binary operations but fails to treat the division by 0 case separately.

Recommendations For TensorFlow versions prior to 2.6.0, update to TensorFlow 2.6.0 or later. For TensorFlow versions 2.5.1 and earlier, update to TensorFlow 2.5.1 or later. For TensorFlow versions 2.4.3 and earlier, update to TensorFlow 2.4.3 or later. For TensorFlow 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.SparseDenseCwiseDiv until a patch is available.
