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.
