CVE-2021-29536

Advisory

Tensorflow-rocm-enhanced 2.1.4, 2.2.3, 2.3.3 and 2.4.2 include a fix for CVE-2021-29536: An attacker can cause a heap buffer overflow in 'QuantizedReshape' by passing in invalid thresholds for the quantization. This is because the implementation (https://github.com/tensorflow/tensorflow/blob/a324ac84e573fba362a5e53d4e74d5de6729933e/tensorflow/core/kernels/quantized_reshape_op.cc#L38-L55) assumes that the 2 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.
