Description GLSAMaker/CVETool Bot gentoo-dev 2020-04-16 14:07:21 UTC
CVE-2020-5215 (https://nvd.nist.gov/vuln/detail/CVE-2020-5215):
  In TensorFlow before 1.15.2 and 2.0.1, converting a string (from Python) to
  a tf.float16 value results in a segmentation fault in eager mode as the
  format checks for this use case are only in the graph mode. This issue can
  lead to denial of service in inference/training where a malicious attacker
  can send a data point which contains a string instead of a tf.float16 value.
  Similar effects can be obtained by manipulating saved models and checkpoints
  whereby replacing a scalar tf.float16 value with a scalar string will
  trigger this issue due to automatic conversions. This can be easily
  reproduced by tf.constant("hello", tf.float16), if eager execution is
  enabled. This issue is patched in TensorFlow 1.15.1 and 2.0.1 with this
  vulnerability patched. TensorFlow 2.1.0 was released after we fixed the
  issue, thus it is not affected. Users are encouraged to switch to TensorFlow
  1.15.1, 2.0.1 or 2.1.0.
