Title: GNU Libgcrypt和GnuPG可预测随机数生成漏洞

Description:

GNU Libgcrypt和GnuPG（GNU Privacy Guard）都是GNU计划开发的基于GnuPG代码的通用加密库。

GNU Libgcrypt 1.6.3-2+deb8u2之前的版本和GnuPG 1.4.18-7+deb8u2之前的版本中的‘mixing’函数存在可预测随机数生成漏洞，攻击者可利用该漏洞从RNG获得4640 bit数据后，轻易预测接下来的160 bit数据。

Severity: 低

Patch Name: GNU Libgcrypt和GnuPG可预测随机数生成漏洞的补丁

Summary

The mixing functions in the random number generator in Libgcrypt before 1.5.6, 1.6.x before 1.6.6, and 1.7.x before 1.7.3 and GnuPG before 1.4.21 make it easier for attackers to obtain the values of 160 bits by leveraging knowledge of the previous 4640 bits.
