CVE-2021-29594: Google Tensorflow

High severity, CVSS 7.8. EPSS: 0.2% chance of exploitation in the next 30 days.

TensorFlow is an end-to-end open source platform for machine learning. TFLite's convolution code(https://github.com/tensorflow/tensorflow/blob/09c73bca7d648e961dd05898292d91a8322a9d45/tensorflow/lite/kernels/conv.cc) has multiple division where the divisor is controlled by the user and not checked to be non-zero. The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3 and TensorFlow 2.1.4, as these are also affected and still in supported range.

Affected products

• Google Tensorflow: before 2.1.4 (fixed in 2.1.4); from 2.2.0, before 2.2.3 (fixed in 2.2.3); from 2.3.0, before 2.3.3 (fixed in 2.3.3); from 2.4.0, before 2.4.2 (fixed in 2.4.2)
