CVE-2021-29536: TensorFlow is an end-to-end open source platform for machine learning. An attacker can cause a heap buffer overflow in `
Summary
TensorFlow, a machine learning platform, has a heap buffer overflow vulnerability (a memory safety bug where code writes beyond allocated memory) in the `QuantizedReshape` function. The vulnerability occurs when an attacker passes empty tensors (multi-dimensional arrays) as threshold inputs, causing the code to incorrectly access memory at position 0 of an empty buffer.
Solution / Mitigation
The fix will be included in TensorFlow 2.5.0. The vulnerability will also be patched in TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3, and TensorFlow 2.1.4.
