PYSEC-2022-156

Tensorflow is an Open Source Machine Learning Framework. TensorFlow's type inference can cause a heap out of bounds read as the bounds checking is done in a DCHECK which is a no-op during production. An attacker can control the inputidx variable such that ix would be larger than the number of...

Tensorflow is an Open Source Machine Learning Framework. TensorFlow's type inference can cause a heap out of bounds read as the bounds checking is done in a DCHECK which is a no-op during production. An attacker can control the inputidx variable such that ix would be larger than the number of...

PYSEC-2022-87

Tensorflow is an Open Source Machine Learning Framework. If a graph node is invalid, TensorFlow can leak memory in the implementation of ImmutableExecutorState::Initialize. Here, we set item-kernel to nullptr but it is a simple OpKernel pointer so the memory that was previously allocated to it...

PYSEC-2022-70

Tensorflow is an Open Source Machine Learning Framework. An attacker can craft a TFLite model that would cause a write outside of bounds of an array in TFLite. In fact, the attacker can override the linked list used by the memory allocator. This can be leveraged for an arbitrary write primitive...

CVE-2022-23561

CVE-2022-23561 affects TensorFlow’s TFLite, enabling out-of-bounds writes by crafting a TFLite model that can corrupt the memory allocator’s linked list. This vulnerability allows an arbitrary write primitive under certain conditions as described in the CVE description. Affected details in connec...

CVE-2022-23557 Division by zero in TFLite

Tensorflow is an Open Source Machine Learning Framework. An attacker can craft a TFLite model that would trigger a division by zero in BiasAndClamp implementation. There is no check that the biassize is non zero. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on...

CVE-2022-23557

TensorFlow/TFLite BiasAndClamp vulnerability: a crafted TFLite model can trigger a division by zero due to missing non-zero bias_size checks in BiasAndClamp. The issue affects TFLite in TensorFlow and will be fixed in TensorFlow 2.8.0, with cherry-picks planned for TensorFlow 2.7.1, 2.6.3, and 2....

CVE-2022-23558 Integer overflow in TFLite array creation

Tensorflow is an Open Source Machine Learning Framework. An attacker can craft a TFLite model that would cause an integer overflow in TfLiteIntArrayCreate. The TfLiteIntArrayGetSizeInBytes returns an int instead of a sizet. An attacker can control model inputs such that computedsize overflows the...

CVE-2022-23558

CVE-2022-23558 describes an integer overflow in TensorFlow’s TFLite path: TfLiteIntArrayCreate alloc_size is derived from TfLiteIntArrayGetSizeInBytes(size), which returns an int instead of a size_t, enabling an attacker-controlled input to overflow computed_size. Affected: TensorFlow/TFLite mode...

CVE-2022-23570 Null-dereference in Tensorflow

Tensorflow is an Open Source Machine Learning Framework. When decoding a tensor from protobuf, TensorFlow might do a null-dereference if attributes of some mutable arguments to some operations are missing from the proto. This is guarded by a DCHECK. However, DCHECK is a no-op in production builds...

CVE-2022-23564 Reachable Assertion in Tensorflow

Tensorflow is an Open Source Machine Learning Framework. When decoding a resource handle tensor from protobuf, a TensorFlow process can encounter cases where a CHECK assertion is invalidated based on user controlled arguments. This allows attackers to cause denial of services in TensorFlow...

CVE-2022-23564

CVE-2022-23564 (TensorFlow) : The issue is a denial-of-service in TensorFlow caused by an invalidated CHECK assertion when decoding a resource handle tensor from protobuf, triggered by user-controlled arguments. Affected: TensorFlow (TF) processes; root cause is an assertion failure path during r...

CVE-2022-23565

CVE-2022-23565 : TensorFlow contains a denial-of-service risk caused by an assertion failure when a SavedModel on disk has duplicated AttrDef entries for an operation. The issue’s root cause is described across connected sources as a SavedModel mismatch that can trigger a crash under certain on-d...

CVE-2022-23562 Integer overflow in Tensorflow

Tensorflow is an Open Source Machine Learning Framework. The implementation of Range suffers from integer overflows. These can trigger undefined behavior or, in some scenarios, extremely large allocations. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on...
