## Overview

Khronos NNEF-Tools nnef through 1.0.10 and nnef-tools through 1.0.11 contain a path traversal vulnerability that allows attackers to write files outside the model directory via crafted variable labels. Attackers can supply a graph.nnef with '../' sequences or absolute paths in labels to create or overwrite '.dat' files when users convert, save, or generate weights.
