CVE-2022-36013 Null-dereference in `mlir::tfg::GraphDefImporter::ConvertNodeDef` in TensorFlow

TensorFlow is an open source platform for machine learning. When mlir::tfg::GraphDefImporter::ConvertNodeDef tries to convert NodeDefs without an op name, it crashes. We have patched the issue in GitHub commit a0f0b9a21c9270930457095092f558fbad4c03e5. The fix will be included in TensorFlow 2.10.0...

GHSA-FQXC-PVF8-2W9V TensorFlow vulnerable to null dereference on MLIR on empty function attributes

Impact Eig can be fed an incorrect Tout input, resulting in a CHECK fail that can trigger a denial of service attack. python import tensorflow as tf import numpy as np arg0=tf.constantvalue=np.random.randomsize=2, 2, shape=2, 2, dtype=tf.float32 arg1=tf.complex128 arg2=True arg3=''...

TensorFlow vulnerable to null dereference on MLIR on empty function attributes

Impact When mlir::tfg::ConvertGenericFunctionToFunctionDef is given empty function attributes, it gives a null dereference. cpp // Import the function attributes with a tf. prefix to match the current // infrastructure expectations. for const auto& namedAttr : func.attr const std::string& name =...

TensorFlow vulnerable to null-dereference in `mlir::tfg::TFOp::nameAttr`

Impact When mlir::tfg::TFOp::nameAttr receives null type list attributes, it crashes. cpp StatusOr GraphDefImporter::ArgNumTypeconst NamedAttrList &attrs, const OpDef::ArgDef &argdef, SmallVectorImpl &types // Check whether a type list attribute is specified. if !argdef.typelistattr.empty if auto...

TensorFlow vulnerable to assertion fail on MLIR empty edge names

Impact When mlir::tfg::ConvertGenericFunctionToFunctionDef is given empty function attributes, it crashes. cpp // We pre-allocate the array of operands and populate it using the // outputnametoposition and controloutputtoposition populated // previously. SmallVector retvalsfunc.retsize +...

GHSA-9X52-887G-FHC2 Out of bounds read in Tensorflow

Impact The TFG dialect of TensorFlow MLIR makes several assumptions about the incoming GraphDef before converting it to the MLIR-based dialect. If an attacker changes the SavedModel format on disk to invalidate these assumptions and the GraphDef is then converted to MLIR-based IR then they can...

Google Tensorflow Buffer Overflow Vulnerability (CNVD-2022-09865)

Google TensorFlow is a suite of end-to-end open source platforms for machine learning from Google USA. Google TensorFlow suffers from a buffer overflow vulnerability that can be exploited by an attacker to change the format of the SavedModel on disk to invalidate these assumptions, and then...

Google Tensorflow code issue vulnerability (CNVD-2022-09866)

Google TensorFlow is a suite of end-to-end open source platforms for machine learning from Google USA. Google TensorFlow has a code issue vulnerability that stems from the simplifyBroadcast function in the MLIR-TFRT infrastructure in TensorFlow being prone to segmentation errors. No detailed...

CVE-2022-23593

Tensorflow is an Open Source Machine Learning Framework. The simplifyBroadcast function in the MLIR-TFRT infrastructure in TensorFlow is vulnerable to a segfault hence, denial of service, if called with scalar shapes. If all shapes are scalar, then maxRank is 0, so we build an empty SmallVector...
