CVE-2021-41227 (CNNVD-202111-556)
中文标题:
Google TensorFlow缓冲区错误漏洞
英文标题:
Arbitrary memory read in `ImmutableConst`
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。 Google TensorFlow 存在缓冲区错误漏洞,该漏洞源于 ImmutableConst 操作可以被诱骗读取任意内存内容。 这是因为 TensorFlow 字符串类(tstring)对内存映射字符串有一个特殊情况,但操作本身不提供对这种数据类型的任何支持。
英文描述:
TensorFlow is an open source platform for machine learning. In affected versions the `ImmutableConst` operation in TensorFlow can be tricked into reading arbitrary memory contents. This is because the `tstring` TensorFlow string class has a special case for memory mapped strings but the operation itself does not offer any support for this datatype. The fix will be included in TensorFlow 2.7.0. We will also cherrypick this commit on TensorFlow 2.6.1, TensorFlow 2.5.2, and TensorFlow 2.4.4, as these are also affected and still in supported range.
