Golang-fips: golang fips zeroed buffer

A vulnerability was found in Golang FIPS OpenSSL. This flaw allows a malicious user to randomly cause an uninitialized buffer length variable with a zeroed buffer to be returned in FIPS mode. It may also be possible to force a false positive match between non-equal hashes when comparing a trusted computed hmac sum to an untrusted input sum if an attacker can send a zeroed buffer in place of a pre-computed sum.  It is also possible to force a derived key to be all zeros instead of an unpredictable value.  This may have follow-on implications for the Go TLS stack.

使用未经初始化的变量

Google Golang 安全漏洞

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，该漏洞源于允许恶意用户在FIPS模式下随机导致未初始化的缓冲区长度变量与零缓
