CVE-2021-37667

TensorFlow: CVE-2021-37667 involves a NULL pointer dereference in UnicodeEncode where the code reads input_splits[0] before validating emptiness. A patch is in commit 2e0ee46f..., fixes to be included in TensorFlow 2.6.0 and backported to 2.5.1, 2.4.3, and 2.3.4. Affected: tf.raw_ops.UnicodeEncod...

CVE-2021-37648

TensorFlow SaveV2 input validation flaw (tf.raw_ops.SaveV2) allows a local attacker to trigger a NULL pointer dereference due to improper input validation in ValidateInputs. The issue was fixed in TensorFlow 2.6.0 (commit 9728c60e...); backports were planned for 2.5.1, 2.4.3, and 2.3.4. Affected ...

CVE-2021-37648 Incorrect validation of `SaveV2` inputs in TensorFlow

TensorFlow is an end-to-end open source platform for machine learning. In affected versions the code for tf.rawops.SaveV2 does not properly validate the inputs and an attacker can trigger a null pointer dereference. The implementation uses ValidateInputs to check that the input arguments are vali...

CVE-2021-37652

TensorFlow Bug: BoostedTreesCreateEnsemble uses a reference-counted resource that was refactored to a smart pointer; when initialization fails, a later scope exit frees the resource even if its refcount is 0, causing a use-after-free. A patch (commit 5ecec9c6fbdbc6be03295685190a45e7eee726ab) fixe...

CVE-2021-37652 Use after free in boosted trees creation in TensorFlow

TensorFlow is an end-to-end open source platform for machine learning. In affected versions the implementation for tf.rawops.BoostedTreesCreateEnsemble can result in a use after free error if an attacker supplies specially crafted arguments. The implementation uses a reference counted resource an...

CVE-2021-37664
