CVE-2021-29518 (CNNVD-202105-997)
中文标题:
Google TensorFlow 代码问题漏洞
英文标题:
Session operations in eager mode lead to null pointer dereferences
漏洞描述
中文描述:
Google TensorFlow是美国谷歌(Google)公司的一套用于机器学习的端到端开源平台。 TensorFlow 2.4.2,2.3.3,2.2.3,2.1.4 存在安全漏洞,该漏洞源于在立即模式下会话操作是无效的。但是用户仍然可以调用与之关联的原始操作,并触发空指针解引用。
英文描述:
TensorFlow is an end-to-end open source platform for machine learning. In eager mode (default in TF 2.0 and later), session operations are invalid. However, users could still call the raw ops associated with them and trigger a null pointer dereference. The implementation(https://github.com/tensorflow/tensorflow/blob/eebb96c2830d48597d055d247c0e9aebaea94cd5/tensorflow/core/kernels/session_ops.cc#L104) dereferences the session state pointer without checking if it is valid. Thus, in eager mode, `ctx->session_state()` is nullptr and the call of the member function is undefined behavior. The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3 and TensorFlow 2.1.4, as these are also affected and still in supported range.
