Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The tensorflow, tensorflow-cpu and tensorflow-gpu packages, versions below 1.15.2 and version 2.0.0, segfault when a Python string is converted to tf.float16 in eager mode. An attacker who supplies a string instead of a float16 value in input data or a saved model can cause a denial of service. Upgrade to 1.15.2 or 2.0.1.
