CVE-2021-29544

5.5 mediumEPSS 0.3%

Medium (5.5) in google tensorflow. EPSS 0.3% chance of exploitation in the next 30 days. Fixed in tensorflow 2.2.0rc0, 2.3.0rc0, 2.3.4.

TensorFlow is an end-to-end open source platform for machine learning. An attacker can trigger a denial of service via a `CHECK`-fail in `tf.raw_ops.QuantizeAndDequantizeV4Grad`. This is because the implementation does not validate the rank of the `input_*` tensors. In turn, this results in the tensors being passes as they are to `QuantizeAndDequantizePerChannelGradientImpl`. However, the `vec<T>` method, requires the rank to 1 and triggers a `CHECK` failure otherwise. The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2 as this is the only other affected version.
