前言

漏扫发现机器上的redis版本有点低，需要升级版本修复漏洞

---

一、漏洞内容

Redis Labs Redis 输入验证错误漏洞(CVE-2022-35951)

Redis 输入验证错误漏洞（CVE-2023-22458）

Redis 安全漏洞(CVE-2023-28856)

二、现状

现在的redis是使用的docker运行的，版本是7.0.4

docker exec -it redis /bin/bash
root@9c719615bb29:/data# redis-cli  -v
redis-cli 7.0.4

三、更新redis

下载镜像

docker pull redis:latest

停止已有的容器

docker stop   redis
docker rm    redis

启动新的容器

docker run --name redis -d -p 6379:6379  -v /data/redis-data:/data --restart=always   redis:latest

四、更新后的版本

1. 查看日志

docker logs redis

2. 查看版本

redis-cli -v
redis-cli 7.2.1

总结

我之前的redis部署把data目录挂载出来了，所以升级比较简单
