5月3日，图像处理软件ImageMagick就被公布出一个严重的0day漏洞(CVE-2016-3714)，攻击者通过此漏洞可执行任意命令，最终窃取重要信息取得服务器控制权。

详细信息参考：https://www.imagemagick.org/discourse-server/viewtopic.php?f=4&t=29588

该漏洞在6.9.3-10、7.0.1-1及以上版本得到修复，下面来看看OneinStack或《lnmp一键安装包》（最新下载OneinStack默认已经升级，无此漏洞）之前版本怎么来通过升级修复这个漏洞，如下：

cd /root/oneinstack   #进入oneinstack工具目录
#cd /root/lnmp  #如果安装使用的是lnmp
tmux   #进入tmux模式下，防止断网导致升级中断
wget http://mirrors.linuxeye.com/scripts/update_ImageMagick.sh  #下载升级脚本
chmod +x update_ImageMagick.sh   #赋权权限
./update_ImageMagick.sh   #升级，注：请勿sh或bash update_ImageMagick.sh方式执行脚本
