      "value": "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."

En el fragmento vinculado, en modo eager, \"ctx-) session_state()\" devuelve \"nullptr\". Dado que el c\u00f3digo elimina inmediatamente la referencia a esto, obtenemos un fallo de segmentaci\u00f3n. El problema es parcheado en el commit 9a133d73ae4b4664d22bd1aa6d654fec13c52ee1 y es publicado en TensorFlow versiones 1.15.4, 2.0.3, 2.1.2, 2.2.1 o 2.3.1"
