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...

Integer overflow in TFLite memory allocation

Impact The TFLite code for allocating TFLiteIntArrays is vulnerable to an integer overflow issue: cc int TfLiteIntArrayGetSizeInBytesint size static TfLiteIntArray dummy; return sizeofdummy + sizeofdummy.data0 size; An attacker can craft a model such that the size multiplier is so large that the...

Division by zero in TFLite's implementation of hashtable lookup

Impact The TFLite implementation of hashtable lookup is vulnerable to a division by zero error: cc const int numrows = SizeOfDimensionvalue, 0; const int rowbytes = value-bytes / numrows; An attacker can craft a model such that values's first dimension would be 0. Patches We have patched the issu...

Heap OOB write in TFLite

Impact A specially crafted TFLite model could trigger an OOB write on heap in the TFLite implementation of ArgMin/ArgMax: cc TfLiteIntArray outputdims = TfLiteIntArrayCreateNumDimensionsinput - 1; int j = 0; for int i = 0; i dataj = SizeOfDimensioninput, i; ++j; If axisvalue is not a value betwee...

Division by zero in TFLite's implementation of `DepthwiseConv`

Impact The implementation of the DepthwiseConv TFLite operator is vulnerable to a division by zero error: cc int numinputchannels = SizeOfDimensioninput, 3; TFLITEENSUREEQcontext, numfilterchannels % numinputchannels, 0; An attacker can craft a model such that input's fourth dimension would be 0...

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...

Division by zero in TFLite's implementation of Split

Impact The implementation of the Split TFLite operator is vulnerable to a division by zero error: cc TFLITEENSUREMSGcontext, inputsize % numsplits == 0, "Not an even split"; const int slicesize = inputsize / numsplits; An attacker can craft a model such that numsplits would be 0. Patches We have...

Division by zero in TFLite's implementation of `SVDF`

Impact The implementation of the SVDF TFLite operator is vulnerable to a division by zero error: cc const int rank = params-rank; ... TFLITEENSUREEQcontext, numfilters % rank, 0; An attacker can craft a model such that params-rank would be 0. Patches We have patched the issue in GitHub commit...

Division by zero in TFLite's implementation of `EmbeddingLookup`

The implementation of the EmbeddingLookup TFLite operator is vulnerable to a division by zero error: cc const int rowsize = SizeOfDimensionvalue, 0; const int rowbytes = value-bytes / rowsize; An attacker can craft a model such that the first dimension of the value input is 0. Patches We have...

Division by zero in TFLite's implementation of `DepthToSpace`

Impact The implementation of the DepthToSpace TFLite operator is vulnerable to a division by zero error: cc const int blocksize = params-blocksize; ... const int inputchannels = input-dims-data3; ... int outputchannels = inputchannels / blocksize / blocksize; An attacker can craft a model such th...

Division by zero in TFLite's convolution code

Impact TFLite's convolution code has multiple division where the divisor is controlled by the user and not checked to be non-zero. For example: cc const int inputsize = NumElementsinput / SizeOfDimensioninput, 0; Patches We have patched the issue in GitHub commit...

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...

Division by zero in TFLite's implementation of `GatherNd`

Impact The reference implementation of the GatherNd TFLite operator is vulnerable to a division by zero error: cc ret.dimstocounti = remainflatsize / paramsshape.Dimsi; An attacker can craft a model such that params input would be an empty tensor. In turn, paramsshape.Dims. would be zero, in at...

Division by zero in TFLite's implementation of `SpaceToDepth`

Impact The Prepare step of the SpaceToDepth TFLite operator does not check for 0 before division. cc const int blocksize = params-blocksize; const int inputheight = input-dims-data1; const int inputwidth = input-dims-data2; int outputheight = inputheight / blocksize; int outputwidth = inputwidth ...

Division by zero in optimized pooling implementations in TFLite

Impact Optimized pooling implementations in TFLite fail to check that the stride arguments are not 0 before calling ComputePaddingHeightWidth. Since users can craft special models which will have params-strideheight,width be zero, this will result in a division by zero. Patches We have patched th...

Division by zero in padding computation in TFLite

Impact The TFLite computation for size of output after padding, ComputeOutSize, does not check that the stride argument is not 0 before doing the division. cc inline int ComputeOutSizeTfLitePadding padding, int imagesize, int filtersize, int stride, int dilationrate = 1 int effectivefiltersize =...
