Advisory

Tensorflow version 2.6.1 includes a fix for CVE-2021-41220: In affected versions, the async implementation of 'CollectiveReduceV2' suffers from a memory leak and a use after free. This occurs due to the asynchronous computation and the fact that objects that have been 'std::move()'d are still accessed. The fix is included in TensorFlow 2.7.0.
