Descriptions

Tensorflow is an Open Source Machine Learning Framework. An attacker can craft a TFLite model that would cause an integer overflow in embedding lookup operations. Both `embedding_size` and `lookup_size` are products of values provided by the user. Hence, a malicious user could trigger overflows in the multiplication. In certain scenarios, this can then result in heap OOB read/write. Users are advised to upgrade to a patched version.

Tensorflow es un Marco de Aprendizaje Automático de Código Abierto. Un atacante puede diseñar un modelo TFLite que cause un desbordamiento de enteros en las operaciones de búsqueda de inserción. Tanto "embedding_size" como "lookup_size" son productos de valores proporcionados por el usuario. Por lo tanto, un usuario malicioso podría desencadenar desbordamientos en la multiplicación. En determinados escenarios, esto puede resultar en una lectura/escritura de OOB de la pila. Se aconseja a usuarios que actualicen a una versión parcheada
