When the BaseCandidateSamplerOp
function receives a value in true_classes
larger than range_max
, a heap oob vuln occurs.
tf.raw_ops.ThreadUnsafeUnigramCandidateSampler(
true_classes=[[0x100000,1]],
num_true = 2,
num_sampled = 2,
unique = False,
range_max = 2,
seed = 2,
seed2 = 2)
We have patched the issue in GitHub commit b389f5c944cadfdfe599b3f1e4026e036f30d2d4.
The fix will be included in TensorFlow 2.11. We will also cherrypick this commit on TensorFlow 2.10.1, 2.9.3, and TensorFlow 2.8.4, as these are also affected and still in supported range.
Please consult our security guide for more information regarding the security model and how to contact us with issues and questions.
