The SparseCountSparseOutput
implementation does not validate that the input arguments form a valid sparse tensor. In particular, there is no validation that the indices
tensor has the same shape as the values
one. The values in these tensors are always accessed in parallel:

Thus, a shape mismatch can result in accesses outside the bounds of heap allocated buffers.
We have patched the issue in 3cbb917b4714766030b28eba9fb41bb97ce9ee02 and will release a patch release.
We recommend users to upgrade to TensorFlow 2.3.1.
