CVE-2020-15266 Information

Description

In Tensorflow before version 2.4.0 when the boxes argument of tf.image.crop_and_resize has a very large value the CPU kernel implementation receives it as a C++ nan floating point value. Attempting to operate on this is undefined behavior which later produces a segmentation fault. The issue is patched in eccb7ec454e6617738554a255d77f08e60ee0808 and TensorFlow 2.4.0 will be released containing the patch. TensorFlow nightly packages after this commit will also have the issue resolved.
