Summary
TensorFlow, an open source machine learning platform, has a vulnerability where an attacker can cause a denial of service (making a service unavailable) by triggering a FPE (floating-point exception, a math error that crashes a program) runtime error in a specific function called `tf.raw_ops.Reverse`. The bug happens because the code divides by the first dimension of a tensor (a multi-dimensional array of numbers) without properly checking if that dimension is zero.
Solution / Mitigation
The fix will be included in TensorFlow 2.5.0. The patch will also be applied to TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3, and TensorFlow 2.1.4.
