CVE-2020-15198: Google Tensorflow

Medium severity, CVSS 5.4. EPSS: 0.5% chance of exploitation in the next 30 days.

In Tensorflow before version 2.3.1, 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. The issue is patched in commit 3cbb917b4714766030b28eba9fb41bb97ce9ee02 and is released in TensorFlow version 2.3.1.

Affected products

• Google Tensorflow: from 2.3.0, before 2.3.1 (fixed in 2.3.1)
