CVE-2023-25668: Out-of-bounds Read (CWE-125)
value: TensorFlow is an open source platform for machine learning. Attackers using Tensorflow prior to 2.12.0 or 2.11.1 can access heap memory which is not in the control of user, leading to a crash or remote code execution. The fix will be included in TensorFlow version 2.12.0 and will also cherrypick this commit on TensorFlow version 2.11.1.
CWE description: The product reads data past the end, or before the beginning, of the intended buffer.
