Name of the Vulnerable Software and Affected Versions RubyGems versions 1.8.24 through 1.8.25 RubyGems versions 2.0.x through 2.0.7 RubyGems versions 2.1.x through 2.1.0 RubyGems version 1.8.23 and earlier

Description The issue allows remote attackers to cause a denial of service via a crafted gem version that triggers a large amount of backtracking in a regular expression in the Gem::Version::VERSION PATTERN in lib/rubygems/version.rb. This can lead to CPU consumption.

Recommendations For RubyGems versions 1.8.24 through 1.8.25, update to version 1.8.26 or later. For RubyGems versions 2.0.x through 2.0.7, update to version 2.0.8 or later. For RubyGems versions 2.1.x through 2.1.0, update to version 2.1.1 or later. For RubyGems version 1.8.23 and earlier, update to version 1.8.23.1 or later. As a temporary workaround, consider restricting the use of the Gem::Version::VERSION PATTERN until a patch is available.
