CVE-2021-37667

Advisory

Tensorflow-rocm-enhanced 2.3.4 and 2.4.3 include a fix for CVE-2021-37667: In affected versions an attacker can cause undefined behavior via binding a reference to null pointer in 'tf.raw_ops.UnicodeEncode'. The implementation (https://github.com/tensorflow/tensorflow/blob/460e000de3a83278fb00b61a16d161b1964f15f4/tensorflow/core/kernels/unicode_ops.cc#L533-L539) reads the first dimension of the 'input_splits' tensor before validating that this tensor is not empty. The Tensorflow team has patched the issue in GitHub commit 2e0ee46f1a47675152d3d865797a18358881d7a6.
