Name of the Vulnerable Software and Affected Versions TensorFlow versions prior to 2.5.0 TensorFlow versions 2.4.2 and earlier TensorFlow versions 2.3.3 and earlier TensorFlow versions 2.2.3 and earlier TensorFlow versions 2.1.4 and earlier

Description The implementation of the OneHot TFLite operator is vulnerable to a division by zero error. An attacker can craft a model such that at least one of the dimensions of indices would be 0, causing the prefix dim size value to become 0.

Recommendations For versions prior to 2.5.0, update to TensorFlow 2.5.0 or later. For versions 2.4.2 and earlier, update to TensorFlow 2.4.2 or later. For versions 2.3.3 and earlier, update to TensorFlow 2.3.3 or later. For versions 2.2.3 and earlier, update to TensorFlow 2.2.3 or later. For versions 2.1.4 and earlier, update to TensorFlow 2.1.4 or later. As a temporary workaround, consider restricting the use of the OneHot TFLite operator until a patch is available.
