      <description>&lt;h3 id=&#34;漏洞概要&#34;&gt;&lt;strong&gt;漏洞概要&lt;/strong&gt;&lt;/h3&gt;&#xA;&lt;p&gt;Rack（Ruby的Web服务器接口）在处理内容类型为 &lt;code&gt;application/x-www-form-urlencoded&lt;/code&gt; 的表单提交时，其 &lt;code&gt;Rack::Request#POST&lt;/code&gt; 方法会将整个请求体不加限制地读入内存。攻击者通过发送巨大的请求体，可导致服务器进程内存耗尽，从而引发拒绝服务攻击。&lt;/p&gt;</description>
