Summary
TensorFlow is an end-to-end open source platform for machine learning. In affected versions an attacker can cause denial of service in applications serving models using `tf.raw_ops.NonMaxSuppressionV5` by triggering a division by 0. The [implementation](https://github.com/tensorflow/tensorflow/blob/460e000de3a83278fb00b61a16d161b1964f15f4/tensorflow/core/kernels/image/non_max_suppression_op.cc#L170-L271) uses a user controlled argument to resize a `std::vector`. However, as `std::vector::resize` takes the size argument as a `size_t` and `output_size` is an `int`, there is an implicit conversion to unsigned. If the attacker supplies a negative value, this conversion results in a crash. A similar issue occurs in `CombinedNonMaxSuppression`. We have patched the issue in GitHub commit 3a7362750d5c372420aa8f0caf7bf5b5c3d0f52d and commit [b5cdbf12ffcaaffecf98f22a6be5a64bb96e4f58. The fix will be included in TensorFlow 2.6.0. We will also cherrypick this commit on TensorFlow 2.5.1, TensorFlow 2.4.3, and TensorFlow 2.3.4, as these are also affected and still in supported range.

We have patched the issue in GitHub commit 3a7362750d5c372420aa8f0caf7bf5b5c3d0f52d and commit [b5cdbf12ffcaaffecf98f22a6be5a64bb96e4f58. The fix will be included in TensorFlow 2.6.0. We will also cherrypick this commit on TensorFlow 2.5.1, TensorFlow 2.4.3, and TensorFlow 2.3.4, as these are also affected and still in supported range.\"},{\"lang\":\"es\",\"value\":\"TensorFlow es una plataforma de código abierto de extremo a extremo para el aprendizaje automático.&#xa0;En las versiones afectadas, un atacante puede causar una denegación de servicio en aplicaciones que sirven modelos que usan \\\"tf.raw_ops.NonMaxSuppressionV5\\\" al activar una división por 0. La [implementación] (https://github.com/tensorflow/tensorflow/blob/460e000de3a83278fb00b61a16d161b1964f15f4/ tensorflow / core / kernels / image / non_max_suppression_op.cc # L170-L271) usa un argumento controlado por el usuario para cambiar el tamaño de un \\\"std :: vector\\\".&#xa0;Sin embargo, como \\\"std :: vector :: resize\\\" toma el argumento de tamaño como un\\\" size_t\\\" y \\\"output_size\\\" es un\\\" int\\\", hay una conversión implícita a unsigned.&#xa0;Si el atacante proporciona un valor negativo, esta conversión resulta en un bloqueo.&#xa0;Un problema similar ocurre en \\\"CombinedNonMaxSuppression\\\".&#xa0;Hemos solucionado el problema en GitHub, commit 3a7362750d5c372420aa8f0caf7bf5b5c3d0f52d y commit [b5cdbf12ffcaaffecf98f22a6be5a64bb96e4f58.&#xa0;La corrección será incluida en TensorFlow versión 2.6.0.&#xa0;También seleccionaremos este commit en TensorFlow versión 2.5.1, TensorFlow versión 2.4.3 y TensorFlow versión 2.3.4, ya que estos también están afectados y aún se encuentran en el rango
