Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
Google Golang是美国谷歌（Google）公司的一种静态强类型、编译型语言。Go的语法接近C语言，但对于变量的声明有所不同。Go支持垃圾回收功能。Go的并行模型是以东尼·霍尔的通信顺序进程（CSP）为基础，采取类似模型的其他语言包括Occam和Limbo，但它也具有Pi运算的特征，比如通道传输。在1.8版本中开放插件（Plugin）的支持，这意味着现在能从Go中动态加载部分函数。 Google Golang 存在安全漏洞。攻击者利用该漏洞导致内存过度增长。
