漏洞描述
中文描述:

TensorFlow是TensorFlow开源的一套用于机器学习的端到端开源平台。 TensorFlow存在代码问题漏洞,攻击者可利用该漏洞可以通过利用来自实现CHECK失败来导致拒绝服务。

英文描述:

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.
