Algorithmic complexity vulnerability in Gem::Version::VERSION_PATTERN in
lib/rubygems/version.rb in RubyGems before 1.8.23.1, 1.8.24 through 1.8.25,
2.0.x before 2.0.8, and 2.1.x before 2.1.0, as used in Ruby 1.9.0 through
2.0.0p247, allows remote attackers to cause a denial of service (CPU
consumption) via a crafted gem version that triggers a large amount of
backtracking in a regular expression.
