CVE-2011-2705

原文の説明

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.

• Ruby = 1.9.0-20060415= 1.9.0-1= 1.8.7-249= 1.9.2= 1.9= 1.9.1 完全一致
