Vulnerability Description
The SecureRandom.random_bytes function in lib/securerandom.rb in Ruby before 1.8.7-p352 and 1.9.x before 1.9.2-p290 relies on PID values for initialization, which makes it easier for context-dependent attackers to predict the result string by leveraging knowledge of random strings obtained in an earlier process with the same PID.

Vulnerability Description
Ruby是一种功能强大的面向对象的脚本语言。 Ruby 1.8.7-p352之前版本和1.9.2-p290之前的1.9.x版本的lib/securerandom.rb中的SecureRandom.random_bytes函数初始化时依赖于PID值。上下文相关的攻击者更易于利用从具有相同PID的进程中获取的随机字符串信息预测结果字符串。
