CVE-2021-41222

Advisory

Tensorflow versions 2.4.4, 2.5.2 and 2.6.1 include a fix for CVE-2021-41222: In affected versions, the implementation of 'SplitV' can trigger a segfault if an attacker supplies negative arguments. This occurs whenever 'size_splits' contains more than one value and at least one value is negative. The fix is included in TensorFlow 2.7.0.

Vulnerability changelog

TensorFlow is an open source platform for machine learning. In affected versions the implementation of `SplitV` can trigger a segfault is an attacker supplies negative arguments. This occurs whenever `size_splits` contains more than one value and at least one value is negative. 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 2.4.4, as these are also affected and still in supported range. See CVE-2021-41222.
