PyPI: tensorflow
CVE-2021-41203
Safety vulnerability ID: SFTY-20211105-71514
Safety legacy ID: pyup.io-42450
Tensorflow versions 2.4.4, 2.5.2 and 2.6.1 include a fix for CVE-2021-41203: In affected versions, an attacker can trigger undefined behavior, integer overflows, segfaults and 'CHECK'-fail crashes if they can change saved checkpoints from outside of TensorFlow. This is because the checkpoints loading infrastructure is missing validation for invalid file formats. https://github.com/tensorflow/tensorflow/security/advisories/GHSA-7pxj-m4jf-r6h2
