一、漏洞信息
 漏洞编号：[CVE-2019-15892](https://nvd.nist.gov/vuln/detail/CVE-2019-15892)
 漏洞归属组件：[varnish](https://gitee.com/src-openeuler/varnish)
 漏洞归属的版本：6.0.0
 CVSS V3.0分值：
  BaseScore：7.5 High
  Vector：CVSS：3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
 漏洞简述：
  An issue was discovered in Varnish Cache before 6.0.4 LTS, and 6.1.x and 6.2.x before 6.2.1. An HTTP/1 parsing failure allows a remote attacker to trigger an assert by sending crafted HTTP/1 requests. The assert will cause an automatic restart with a clean cache, which makes it a Denial of Service attack.

二、漏洞分析结构反馈
 影响性分析说明：
    在6.0.4 LTS之前的Varnish Cache中以及在6.2.1之前的6.1.x和6.2.x中发现了一个问题。HTTP / 1解析失败使远程攻击者可以通过发送精心制作的HTTP / 1请求来触发断言。该断言将导致使用干净的缓存自动重启，这使其成为拒绝服务攻击。
