CVE-2020-15204 Information

Description

In eager mode TensorFlow before versions 1.15.4 2.0.3 2.1.2 2.2.1 and 2.3.1 does not set the session state. Hence calling tf.raw_ops.GetSessionHandle or tf.raw_ops.GetSessionHandleV2 results in a null pointer dereference In linked snippet in eager mode ctx-session_state() returns nullptr. Since code immediately dereferences this we get a segmentation fault. The issue is patched in commit 9a133d73ae4b4664d22bd1aa6d654fec13c52ee1 and is released in TensorFlow versions 1.15.4 2.0.3 2.1.2 2.2.1 or 2.3.1.
