CVE-2021-41214: Access of Uninitialized Pointer

TensorFlow is an open source platform for machine learning. In affected versions the shape inference code for tf.ragged.cross has an undefined behavior due to binding a reference to nullptr. The fix will be included in TensorFlow 2.7.0. We will also cherrypick this commit on TensorFlow 2.6.1,...

RUSTSEC-2021-0122 Generated code can read and write out of bounds in safe code

Code generated by flatbuffers' compiler is unsafe but not marked as such. See https://github.com/google/flatbuffers/issues/6627 for details. For example, if generated code is used to decode malformed or untrusted input, undefined behavior and thus security vulnerabilities is possible even without...
