CVE-2021-29535

Advisory

Tensorflow-rocm 2.1.4, 2.2.3, 2.3.3, 2.4.2, and 2.5.0 include a fix for CVE-2021-29535: An attacker can cause a heap buffer overflow in 'QuantizedMul' by passing in invalid thresholds for the quantization. This is because the implementation (https://github.com/tensorflow/tensorflow/blob/87cf4d3ea9949051e50ca3f071fc909538a51cd0/tensorflow/core/kernels/quantized_mul_op.cc#L287-L290) assumes that the 4 arguments are always valid scalars and tries to access the numeric value directly. However, if any of these tensors is empty, then '.flat<T>()' is an empty buffer and accessing the element at position 0 results in overflow.
