Stack overflow

Tensorflow is an Open Source Machine Learning Framework. Multiple operations in TensorFlow can be used to trigger a denial of service via CHECK-fails i.e., assertion failures. This is similar to TFSA-2021-198 and has similar fixes. We have patched the reported issues in multiple GitHub commits. I...

PYSEC-2022-49

Tensorflow is an Open Source Machine Learning Framework. The estimator for the cost of some convolution operations can be made to execute a division by 0. The function fails to check that the stride argument is strictly positive. Hence, the fix is to add a check for the stride argument to ensure ...

CVE-2022-21729

The vulnerability CVE-2022-21729 affects TensorFlow: the UnravelIndex implementation is vulnerable to a division-by-zero caused by an integer overflow in the unravel_index_op. The issue is addressed with a fix in TensorFlow 2.8.0, with cherry-picks to older supported releases TensorFlow 2.7.1, 2....

CVE-2022-21729 Overflow and uncaught divide by zero in Tensorflow

Tensorflow is an Open Source Machine Learning Framework. The implementation of UnravelIndex is vulnerable to a division by zero caused by an integer overflow bug. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlo...

CVE-2022-21725

TensorFlow CVE-2022-21725 describes a vulnerability in the cost estimator for some convolution operations where the stride is not properly validated, enabling a division-by-zero scenario. The issue is caused by the estimator failing to ensure the stride argument is strictly positive. The fix is t...

Integer overflow

Tensorflow is an Open Source Machine Learning Framework. The implementation of AddManySparseToTensorsMap is vulnerable to an integer overflow which results in a CHECK-fail when building new TensorShape objects so, an assert failure based denial of service. We are missing some validation on the...

Design/Logic Flaw

Tensorflow is an Open Source Machine Learning Framework. The implementation of ThreadPoolHandle can be used to trigger a denial of service attack by allocating too much memory. This is because the numthreads argument is only checked to not be negative, but there is no upper bound on its value. Th...

Tensorflow is an Open Source Machine Learning Framework. The implementation of StringNGrams can be used to trigger a denial of service attack by causing an out of memory condition after an integer overflow. We are missing a validation on padwitdh and that result in computing a negative value for...
