Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
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 1.15之前版本中的UnsortedSegmentSum存在缓冲区错误漏洞，该漏洞源于程序没有正确检查边界。本地攻击者可利用该漏洞在系统上执行任意代码或导致应用程序崩溃。

Vulnerability Title
Heap buffer overflow in `UnsortedSegmentSum` in TensorFlow
Source: CVE Program / CVE List V5
Vulnerability Description
In TensorFlow before 1.15, a heap buffer overflow in UnsortedSegmentSum can be produced when the Index template argument is int32. In this case data_size and num_segments fields are truncated from int64 to int32 and can produce negative numbers, resulting in accessing out of bounds heap memory. This is unlikely to be exploitable and was detected and fixed internally in TensorFlow 1.15 and 2.0.
