Ubuntu Security Notice 1583-1 - It was discovered that Ruby incorrectly allowed untainted strings to be modified in protective safe levels. An attacker could use this flaw to bypass intended access restrictions. John Firebaugh discovered that the RubyGems remote gem fetcher did not properly verify SSL certificates. A remote attacker could exploit this to perform a man in the middle attack to alter gem files being downloaded for installation. Various other issues were also addressed.
