PyPI: tensorflow-macos
CVE-2021-41208
Safety vulnerability ID: SFTY-20211105-15599
Safety legacy ID: pyup.io-58387
Tensorflow-macos versions 2.5.3, 2.6.3 and 2.7.1 include a fix for CVE-2021-41208: In affected versions, the code for boosted trees in TensorFlow is still missing validation. As a result, attackers can trigger denial of service (via dereferencing 'nullptr's or via 'CHECK'-failures) as well as abuse undefined behavior (binding references to 'nullptr's). An attacker can also read and write from heap buffers, depending on the API that gets used and the arguments that are passed to the call. Given that the boosted trees implementation in TensorFlow is unmaintained, it is recommend to no longer use these APIs. TensorFlow's boosted trees APIs will be deprecated in subsequent releases. https://github.com/tensorflow/tensorflow/security/advisories/GHSA-57wx-m983-2f88 https://github.com/tensorflow/tensorflow/commit/5c8c9a8bfe750f9743d0c859bae112060b216f5c https://github.com/tensorflow/tensorflow/security/advisories/GHSA-h6gw-r52c-724r
