GHSA-Q3G3-H9R4-PRRC Reference binding to nullptr and heap OOB in binary cwise ops

Impact An attacker can cause undefined behavior via binding a reference to null pointer in all binary cwise operations that don't require broadcasting e.g., gradients of binary cwise operations: python import tensorflow as tf tf.rawops.SqrtGrady=4, 16,dy= The implementation assumes that the two...

PYSEC-2021-306

TensorFlow is an end-to-end open source platform for machine learning. In affected versions the implementations of pooling in TFLite are vulnerable to division by 0 errors as there are no checks for divisors not being 0. We have patched the issue in GitHub commit...

PYSEC-2021-303

TensorFlow is an end-to-end open source platform for machine learning. In affected versions the implementation of SVDF in TFLite is vulnerable to a null pointer error. The GetVariableInput function can return a null pointer but GetTensorData assumes that the argument is always a valid tensor...

CVE-2021-32631

Common is a package of common modules that can be accessed by NIMBLE services. Common before commit number 3b96cb0293d3443b870351945f41d7d55cb34b53 did not properly verify the signature of JSON Web Tokens. This allows someone to forge a valid JWT. Being able to forge JWTs may lead to authenticati...

CVE-2021-32631

CVE-2021-32631 affects the NIMBLE Common package. Before commit 3b96cb0293d3443b870351945f41d7d55cb34b53, it did not properly verify JWT signatures, enabling forging of valid JWTs and potential authentication bypasses. A patch was introduced in that commit; as a workaround, the parseClaimsJws met...

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-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-JHQ9-WM9M-CF89 CHECK-failure in `UnsortedSegmentJoin`

Impact An attacker can cause a denial of service by controlling the values of numsegments tensor argument for UnsortedSegmentJoin: python import tensorflow as tf inputs = tf.constant, dtype=tf.string segmentids = tf.constant, dtype=tf.int32 numsegments = tf.constant, dtype=tf.int32 separator = ''...

GHSA-VQW6-72R7-FGW7 OOB read in `MatrixTriangularSolve`

Impact The implementation of MatrixTriangularSolve fails to terminate kernel execution if one validation condition fails: cc void ValidateInputTensorsOpKernelContext ctx, const Tensor& in0, const Tensor& in1 override OPREQUIRES ctx, in0.dims = 2, errors::InvalidArgument"In0 ndims must be = 2: ",...

PT-2021-18367 · Google · Tensorflow

Name of the Vulnerable Software and Affected Versions: TensorFlow versions prior to 2.5.0 TensorFlow version 2.4.2 TensorFlow version 2.3.3 TensorFlow version 2.2.3 TensorFlow version 2.1.4 Description: The implementation of TrySimplify has undefined behavior due to dereferencing a null pointer i...

PYSEC-2020-325

In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, if a TFLite saved model uses the same tensor as both input and output of an operator, then, depending on the operator, we can observe a segmentation fault or just memory corruption. We have patched the issue in d58c96946b a...

MatrixSSL < 4.0.2 - Stack Buffer Overflow Verifying x.509 Certificates

I happened to notice that a public X.509 certificate testcase for CVE-2014-1569 caused a stack buffer overflow in MatrixSSL. I cleaned up the testcase a bit, to make a better demonstration. You can test it with the certValidate tool that comes with MatrixSSL. $ gdb -q --args...
