CVE-2021-29540

Advisory

Tensorflow-rocm 2.1.4, 2.2.3, 2.3.3, 2.4.2, and 2.5.0 include a fix for CVE-2021-29540: TensorFlow is an end-to-end open source platform for machine learning. An attacker can cause a heap buffer overflow to occur in 'Conv2DBackpropFilter'. This is because the implementation (https://github.com/tensorflow/tensorflow/blob/1b0296c3b8dd9bd948f924aa8cd62f87dbb7c3da/tensorflow/core/kernels/conv_grad_filter_ops.cc#L495-L497) computes the size of the filter tensor but does not validate that it matches the number of elements in 'filter_sizes'. Later, when reading/writing to this buffer, code uses the value computed here, instead of the number of elements in the tensor.
