In affected versions the strided slice implementation in TFLite has a logic bug which can allow an attacker to trigger an infinite loop. This arises from newly introduced support for [ellipsis in axis definition](https://github.com/tensorflow/tensorflow/blob/149562d49faa709ea80df1d99fc41d005b81082a/tensorflow/lite/kernels/strided_slice.cc#L103-L122). An attacker can craft a model such that `ellipsis_end_idx` is smaller than `i` (e.g., always negative). In this case, the inner loop does not increase `i` and the `continue` statement causes execution to skip over the preincrement at the end of the outer loop. We have patched the issue in GitHub commit dfa22b348b70bb89d6d6ec0ff53973bacb4f4695. TensorFlow 2.6.0 is the only affected version."},{"lang":"es","value":"TensorFlow es una plataforma de código abierto de extremo a extremo para el aprendizaje automático. En las versiones afectadas, la implementación strided slice en TFLite presenta un fallo lógico que puede permitir a un atacante desencadenar un bucle infinito. Esto se debe al soporte recientemente introducido para [ellipsis en la definición de ejes](https://github.com/tensorflow/tensorflow/blob/149562d49faa709ea80df1d99fc41d005b81082a/tensorflow/lite/kernels/strided_slice.cc#L103-L122). Un atacante puede diseñar un modelo tal que \"ellipsis_end_idx\" sea menor que \"i\" (por ejemplo, siempre negativo). En este caso, el bucle interno no incrementa \"i\" y la sentencia \"continue\" hace que la ejecución se salte el preincremento al final del bucle externo.
