722415: CVE-2011-2686 CVE-2011-2705 CVE-2011-3009 ruby: Properly initialize the random number generator when forking new process

The MITRE CVE dictionary describes this issue as:

Ruby before 1.8.7-p352 does not reset the random seed upon forking, which makes it easier for context-dependent attackers to predict the values of random numbers by leveraging knowledge of the number sequence obtained in a different child process, a related issue to CVE-2003-0900. NOTE: this issue exists because of a regression during Ruby 1.8.6 development.
