PYSEC-2021-395

TensorFlow is an open source platform for machine learning. In affected versions while calculating the size of the output within the tf.range kernel, there is a conditional statement of type int64 = condition ? int64 : double. Due to C++ implicit conversion rules, both branches of the condition...

PYSEC-2021-825

TensorFlow is an open source platform for machine learning. In affected versions the shape inference code for AllToAll can be made to execute a division by 0. This occurs whenever the splitcount argument is 0. The fix will be included in TensorFlow 2.7.0. We will also cherrypick this commit on...

CVE-2021-41208

TensorFlow is an open source platform for machine learning. In affected versions the code for boosted trees in TensorFlow is still missing validation. As a result, attackers can trigger denial of service via dereferencing nullptrs or via CHECK-failures as well as abuse undefined behavior binding...

PYSEC-2021-826

TensorFlow is an open source platform for machine learning. In affected versions the code for sparse matrix multiplication is vulnerable to undefined behavior via binding a reference to nullptr. This occurs whenever the dimensions of a or b are 0 or less. In the case on one of these is 0, an empt...

PYSEC-2021-818

TensorFlow is an open source platform for machine learning. In affected versions the shape inference code for QuantizeV2 can trigger a read outside of bounds of heap allocated array. This occurs whenever axis is a negative value less than -1. In this case, we are accessing data before the start o...

PYSEC-2021-812

TensorFlow is an open source platform for machine learning. In affected versions during TensorFlow's Grappler optimizer phase, constant folding might attempt to deep copy a resource tensor. This results in a segfault, as these tensors are supposed to not change. The fix will be included in...

CVE-2021-41215 Null pointer exception in `DeserializeSparse`

TensorFlow is an open source platform for machine learning. In affected versions the shape inference code for DeserializeSparse can trigger a null pointer dereference. This is because the shape inference function assumes that the serializesparse tensor is a tensor with positive rank and having 3 ...

PYSEC-2021-609

TensorFlow is an open source platform for machine learning. In affected versions if tf.image.resize is called with a large input argument then the TensorFlow process will crash due to a CHECK-failure caused by an overflow. The number of elements in the output tensor is too much for the int64t typ...

PYSEC-2021-390

TensorFlow is an open source platform for machine learning. In affected versions TensorFlow allows tensor to have a large number of dimensions and each dimension can be as large as desired. However, the total number of elements in a tensor must fit within an int64t. If an overflow occurs,...

PYSEC-2021-608

TensorFlow is an open source platform for machine learning. In affected versions if tf.tile is called with a large input argument then the TensorFlow process will crash due to a CHECK-failure caused by an overflow. The number of elements in the output tensor is too much for the int64t type and th...

PYSEC-2021-394

TensorFlow is an open source platform for machine learning. In affeced versions during execution, EinsumHelper::ParseEquation is supposed to set the flags in inputhasellipsis vector and outputhasellipsis boolean to indicate whether there is ellipsis in the corresponding inputs and output. However...

RM: calibre/buster-backports -- ROM; no security support; bpo10s of a newer version are impossible

Dear Backports admins, I am requesting the removal of calibre from buster-backports, because it has no security support and because newer versions of Calibre depend on a newer Qt version that cannot be backported. I delayed this request until Bullseye was released, so that users would have a...

GHSA-CM5X-837X-JF3C Division by 0 in inplace operations

Impact An attacker can cause a floating point exception by calling inplace operations with crafted arguments that would result in a division by 0: python import tensorflow as tf tf.rawops.InplaceSubx=,i=-99,-1,-1,v=1,1,1 The implementation has a logic error: it should skip processing if x and v a...

GHSA-F5CX-5WR3-5QRC Reference binding to nullptr in boosted trees

GHSA-CFPJ-3Q4C-JHVR Division by zero in TFLite

Impact The implementation of fully connected layers in TFLite is vulnerable to a division by zero error: cc const int batchsize = inputsize / filter-dims-data1; An attacker can craft a model such that filter-dims-data1 is 0. Patches We have patched the issue in GitHub commit...

PYSEC-2021-801

TensorFlow is an end-to-end open source platform for machine learning. In affected versions when running shape functions, some functions such as MutableHashTableShape produce extra output information in the form of a ShapeAndType struct. The shapes embedded in this struct are owned by an inferenc...
