Impact
An attacker can trigger a crash via a floating point exception in
tf.raw_ops.ResourceGather
:The implementation computes the value of a value,
batch_size
, and then divides by it without checking that this value is not 0.Patches
We have patched the issue in GitHub commit ac117ee8a8ea57b73d34665cdf00ef3303bc0b11.
The fix will be included in TensorFlow 2.6.0. We will also cherrypick this commit on TensorFlow 2.5.1, TensorFlow 2.4.3, and TensorFlow 2.3.4, as these are also affected and still in supported range.
