TensorFlow is an open source platform for machine learning. Prior to versions 2.12.0 and 2.11.1, there is a heap buffer overflow in TAvgPoolGrad. A fix is included in TensorFlow 2.12.0 and 2.11.1.
OpenSSL has a `modified` bit that it can set on on `X509_NAME` objects. If this bit is set then the object is not thread-safe even when it appears the code is not modifying the value. Thanks to David Benjamin (Google) for reporting this issue.
`SubjectAlternativeName` and `ExtendedKeyUsage` arguments were parsed using the OpenSSL function `X509V3_EXT_nconf`. This function parses all input using an OpenSSL mini-language which can perform arbitrary file reads. Thanks to David Benjamin (Google) for reporting this issue.
These functions would crash when the context argument was None with certain extension types. Thanks to David Benjamin (Google) for reporting this issue.
### Impact If the parameter `indices` for `DynamicStitch` does not match the shape of the parameter `data`, it can trigger an stack OOB read. ```python import tensorflow as tf func = tf.raw_ops.DynamicStitch para={'indices': [[0xdeadbeef], [405], [519], [758], [1015]], 'data': [[110.27793884277344], [120.29475402832031], [157.2418212890625], [157.2626953125], [188.45382690429688]]} y = func(**para) ``` ### Patches We have patched the issue in GitHub commit [ee004b18b976eeb5a758020af8880236cd707d05](https://github.com/tensorflow/tensorflow/commit/ee004b18b976eeb5a758020af8880236cd707d05). The fix will be included in TensorFlow 2.12. We will also cherrypick this commit on TensorFlow 2.11.1. ### For more information Please consult [our security guide](https://github.com/tensorflow/tensorflow/blob/master/SECURITY.md) for more information regarding the security model and how to contact us with issues and questions. ### Attribution This has been reported via Google OSS VRP.
