Name of the Vulnerable Software and Affected Versions TensorFlow versions prior to 2.7.0 TensorFlow versions 2.6.1 and earlier TensorFlow versions 2.5.2 and earlier TensorFlow versions 2.4.4 and earlier

Description 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.

Recommendations For versions prior to 2.7.0, update to TensorFlow 2.7.0 or later. For versions 2.6.1 and earlier, update to TensorFlow 2.6.1 or later. For versions 2.5.2 and earlier, update to TensorFlow 2.5.2 or later. For versions 2.4.4 and earlier, update to TensorFlow 2.4.4 or later. As a temporary workaround, consider restricting access to the checkpoints loading infrastructure until a patch is available.
