CVE-2021-41208

CVE-2021-41208 involves TensorFlow boosted trees code with missing validation. The root cause is incomplete validation in boosted trees APIs, enabling a local attacker to trigger denial of service (via dereferencing null pointers or CHECK failures) and to cause undefined behavior (binding referen...

CVE-2021-41207 Division by zero in `ParallelConcat`

CVE-2021-41207

TensorFlow ParallelConcat vulnerability (CVE-2021-41207) arises from insufficient input validation in the ParallelConcat implementation, which can lead to a division by zero in affected TensorFlow versions. The issue affects multiple releases and is slated to be fixed in TensorFlow 2.7.0; Sony ch...

CVE-2021-41202 Overflow/crash in `tf.range`

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...

CVE-2021-41202

The CVE-2021-41202 family describes an overflow in TensorFlow's tf.range kernel caused by a conditional int64 = condition ? int64 : double, where implicit C++ casting to double truncates the result. Affected are TF releases in the 2.4.x–2.7.x range (including 2.7.0 and cherry-picks to 2.6.1, 2.5....

CVE-2021-41209 FPE in convolutions with zero size filters

TensorFlow is an open source platform for machine learning. In affected versions the implementations for convolution operators trigger a division by 0 if passed empty filter tensor arguments. The fix will be included in TensorFlow 2.7.0. We will also cherrypick this commit on TensorFlow 2.6.1,...

CVE-2021-41223

TensorFlow is an open source platform for machine learning. In affected versions the implementation of FusedBatchNorm kernels is vulnerable to a heap OOB access. The fix will be included in TensorFlow 2.7.0. We will also cherrypick this commit on TensorFlow 2.6.1, TensorFlow 2.5.2, and TensorFlow...

CVE-2021-41217

TensorFlow is an open source platform for machine learning. In affected versions the process of building the control flow graph for a TensorFlow model is vulnerable to a null pointer exception when nodes that should be paired are not. This occurs because the code assumes that the first node in th...

CVE-2021-41215

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 ...

CVE-2021-41224

TensorFlow is an open source platform for machine learning. In affected versions the implementation of SparseFillEmptyRows can be made to trigger a heap OOB access. This occurs whenever the size of indices does not match the size of values. The fix will be included in TensorFlow 2.7.0. We will al...
