Detailsinfo

A vulnerability was found in TensorFlow up to 2.2.0/2.3.0 (Artificial Intelligence Software). It has been declared as critical. This vulnerability affects the function dlpack.to_dlpack. The manipulation as part of a Argument leads to a uninitialized resource vulnerability. The CWE definition for the vulnerability is CWE-908. The product uses or accesses a resource that has not been initialized. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

In Tensorflow before versions 2.2.1 and 2.3.1, the implementation of `dlpack.to_dlpack` can be made to use uninitialized memory resulting in further memory corruption. This is because the pybind11 glue code assumes that the argument is a tensor. However, there is nothing stopping users from passing in a Python object instead of a tensor. The uninitialized memory address is due to a `reinterpret_cast` Since the `PyObject` is a Python object, not a TensorFlow Tensor, the cast to `EagerTensor` fails. The issue is patched in commit 22e07fb204386768e5bcbea563641ea11f96ceb8 and is released in TensorFlow versions 2.2.1, or 2.3.1.

The weakness was presented 09/25/2020 (GitHub Repository). The advisory is available at github.com. This vulnerability was named CVE-2020-15193 since 06/25/2020. The attack can be initiated remotely. A single authentication is needed for exploitation. Technical details are known, but there is no available exploit.

Upgrading to version 2.2.1 or 2.3.1 eliminates this vulnerability.
