Summary
TensorFlow, a machine learning platform, has a vulnerability where an attacker can cause a denial of service (making the system crash or stop responding) by triggering a failed safety check when converting sparse tensors (data structures with mostly empty values) to CSR sparse matrices. The bug happens because the code tries to access memory locations that are outside the bounds of allocated space, which can corrupt data.
Solution / Mitigation
The fix will be included in TensorFlow 2.5.0. It will also be backported (applied to older versions still being supported) to TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3, and TensorFlow 2.1.4.
