Overview

tensorflow is a machine learning framework.

Affected versions of this package are vulnerable to Out-of-Bounds. During validation at model loading time. the -1 index is a valid tensor index for any operator, including those that don't expect optional inputs and including for output tensors. This allows writing and reading from outside the bounds of heap allocated arrays, although only at a specific offset from the start of these arrays. This results in both read and write gadgets, albeit very limited in scope.
