A flaw was found in rubygem-activesupport. RubyGem’s activesupport gem is vulnerable to a denial of service caused by a regular expression denial of service (ReDoS) flaw in Inflector.underscore. By sending a specially-crafted regex input, a remote attacker can use large amounts of CPU and memory, resulting in a denial of service.
