Impact The implementation of the OneHot TFLite operator is vulnerable to a division by zero error: cc int prefixdimsize = 1; for int i = 0; i dims-datai; const int suffixdimsize = NumElementsopcontext.indices / prefixdimsize; An attacker can craft a model such that at least one of the dimensions ...

GHSA-97WF-P777-86JQ 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...

GHSA-PMPR-55FJ-R229 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...

GHSA-V52P-HFJF-WG88 Division by zero in TFLite's implementation of `SpaceToBatchNd`

Impact The implementation of the SpaceToBatchNd TFLite operator is vulnerable to a division by zero error: cc TFLITEENSUREEQcontext, finaldimsize % blockshapedim, 0; outputsize-datadim + 1 = finaldimsize / blockshapedim; An attacker can craft a model such that one dimension of the block input is ...

GHSA-4VRF-FF7V-HPGR 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...

GHSA-VF94-36G5-69V8 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...

GHSA-CFX7-2XPC-8W4H Division by zero in TFLite's implementation of `BatchToSpaceNd`

Impact The implementation of the BatchToSpaceNd TFLite operator is vulnerable to a division by zero error: cc TFLITEENSUREEQcontext, outputbatchsize % blockshapedim, 0; outputbatchsize = outputbatchsize / blockshapedim; An attacker can craft a model such that one dimension of the block input is 0...

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...

GHSA-CWV3-863G-39VX Stack overflow due to looping TFLite subgraph

Impact TFlite graphs must not have loops between nodes. However, this condition was not checked and an attacker could craft models that would result in infinite loop during evaluation. In certain cases, the infinite loop would be replaced by stack overflow due to too many recursive calls. For...

GHSA-VFR4-X8J2-3RF9 Division by zero in TFLite's implementation of `TransposeConv`

Impact The optimized implementation of the TransposeConv TFLite operator is vulnerable to a division by zero error: cc int heightcol = height + padt + padb - filterh / strideh + 1; int widthcol = width + padl + padr - filterw / stridew + 1; An attacker can craft a model such that strideh,w values...

GHSA-J7RM-8WW4-XX2G 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 ...

GHSA-26J7-6W8W-7922 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...

GHSA-MV78-G7WQ-MHP4 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 =...
