ruby-nokogiri is vulnerable to denial of service (DoS) attacks. The library fails to check the return value from xmlTextReaderExpand in the method Nokogiri::XML::Reader#attribute_hash which may lead to a null pointer exception when invalid markup is being parsed, causing denial of service conditions.
