Out-of-bounds

TensorFlow is an end-to-end open source platform for machine learning. An attacker can force accesses outside the bounds of heap allocated arrays by passing in invalid tensor values to tf.rawops.RaggedCross. This is because the...

Design/Logic Flaw

TensorFlow is an end-to-end open source platform for machine learning. Specifying a negative dense shape in tf.rawops.SparseCountSparseOutput results in a segmentation fault being thrown out from the standard library as std::vector invariants are broken. This is because the...

Input validation

TensorFlow is an end-to-end open source platform for machine learning. Incomplete validation in SparseReshape results in a denial of service based on a CHECK-failure. The...

Design/Logic Flaw

TensorFlow is an end-to-end open source platform for machine learning. An attacker can trigger a denial of service via a CHECK-fail in tf.rawops.SparseConcat. This is because the...

Design/Logic Flaw

TensorFlow is an end-to-end open source platform for machine learning. Incomplete validation in tf.rawops.CTCLoss allows an attacker to trigger an OOB read from heap. The fix will be included in TensorFlow 2.5.0. We will also cherrypick these commits on TensorFlow 2.4.2, TensorFlow 2.3.3,...
