GHSA-RGVQ-PCVF-HX75 Heap OOB and null pointer dereference in `RaggedTensorToTensor`

Impact Due to lack of validation in tf.rawops.RaggedTensorToTensor, an attacker can exploit an undefined behavior if input arguments are empty: python import tensorflow as tf shape = tf.constant-1, -1, shape=2, dtype=tf.int64 values = tf.constant, shape=0, dtype=tf.int64 defaultvalue =...

GHSA-H4PC-GX2W-F2XV Heap OOB read in TFLite

Impact A specially crafted TFLite model could trigger an OOB read on heap in the TFLite implementation of SplitV: cc const int inputsize = SizeOfDimensioninput, axisvalue; If axisvalue is not a value between 0 and NumDimensionsinput, then the SizeOfDimension function will access data outside the...

GHSA-9C84-4HX6-XMM4 Integer overflow in TFLite concatentation

Impact The TFLite implementation of concatenation is vulnerable to an integer overflow issue: cc for int d = 0; d dims-size; ++d if d == axis sumaxis += t-dims-dataaxis; else TFLITEENSUREEQcontext, t-dims-datad, t0-dims-datad; An attacker can craft a model such that the dimensions of one of the...

GHSA-JJR8-M8G8-P6WV Null pointer dereference in TFLite's `Reshape` operator

Impact The fix for CVE-2020-15209 missed the case when the target shape of Reshape operator is given by the elements of a 1-D tensor. As such, the fix for the vulnerability allowed passing a null-buffer-backed tensor with a 1D shape: cc if tensor-data.raw == nullptr && tensor-bytes 0 if...

Heap OOB read in TFLite's implementation of `Minimum` or `Maximum`

Impact The implementations of the Minimum and Maximum TFLite operators can be used to read data outside of bounds of heap allocated objects, if any of the two input tensor arguments are empty. This is because the broadcasting implementation indexes in both tensors with the same index but does not...

GHSA-XVJM-FVXX-Q3HV CHECK-fail due to integer overflow

Impact An attacker can trigger a denial of service via a CHECK-fail in caused by an integer overflow in constructing a new tensor shape: python import tensorflow as tf inputlayer = 260-1 sparsedata = tf.rawops.SparseSplit splitdim=1, indices=0, 0, 0, 1, 0, 2, 4, 3, 5, 0, 5, 1, values=1.0, 1.0, 1....
