CVE-2021-37641

Advisory

Tensorflow-rocm 2.3.4, 2.4.3, 2.5.1 and 2.6.0 include a fix for CVE-2021-37641: In affected versions if the arguments to 'tf.raw_ops.RaggedGather' don't determine a valid ragged tensor code can trigger a read from outside of bounds of heap allocated buffers. The implementation (https://github.com/tensorflow/tensorflow/blob/8d72537c6abf5a44103b57b9c2e22c14f5f49698/tensorflow/core/kernels/ragged_gather_op.cc#L70) directly reads the first dimension of a tensor shape before checking that said tensor has rank of at least 1 (i.e., it is not a scalar). Furthermore, the implementation does not check that the list given by 'params_nested_splits' is not an empty list of tensors. The Tensorflow team has patched the issue in GitHub commit a2b743f6017d7b97af1fe49087ae15f0ac634373.
