Descriptions

TensorFlow is an open source platform for machine learning. When printing a tensor, we get it's data as a `const char*` array (since that's the underlying storage) and then we typecast it to the element type. However, conversions from `char` to `bool` are undefined if the `char` is not `0` or `1`, so sanitizers/fuzzers will crash. The issue has been patched in GitHub commit `1be74370327`. The fix will be included in TensorFlow 2.11.0. We will also cherrypick this commit on TensorFlow 2.10.1, TensorFlow 2.9.3, and TensorFlow 2.8.4, as these are also affected and still in supported range.

TensorFlow es una plataforma de código abierto para aprendizaje automático. Al imprimir un tensor, obtenemos sus datos como una matriz `const char*` (ya que ese es el almacenamiento subyacente) y luego los encasillamos al tipo de elemento. Sin embargo, las conversiones de `char` a `bool` no están definidas si `char` no es `0` o `1`, por lo que los sanitizadores/fuzzers fallarán. El problema se solucionó en el commit de GitHub `1be74370327`. La solución se incluirá en TensorFlow 2.11.0. También seleccionaremos este commit en TensorFlow 2.10.1, TensorFlow 2.9.3 y TensorFlow 2.8.4, ya que estos también se ven afectados y aún se encuentran en el rango admitido.
