检测Linux glibc幽灵漏洞和修补漏洞

1.首先安装rpm : sudo apt-get install rpm  

wget -OGHOST-test.sh http://www.antian365.com/lab/linux0day/GHOST-test.sh.txt  

sudo chmod -R 0777 GHOST-test.sh  

./GHOST-test.sh

 如果执行./GHOST-test.sh 输出

Vulnerable glibc version <= 2.17-54
Vulnerable glibc version <= 2.5-122
Vulnerable glibc version <= 2.12-1.148
Detected glibc version . revision 
This system is vulnerable to CVE-2015-0235. <https://access.redhat.com/security/cve/CVE-2015-0235>
Please refer to <https://access.redhat.com/articles/1332213> for remediation steps

如果存在漏洞则会显示“vulnerable”

2修复方法：
1. Ubuntu/Debian
在Ubuntu/Debian上执行以下命令进行修复，修复后需要重启。
apt-get update && apt-get -y install libc6
2.Centos
在Centos上执行“yumupdate glibc”后会有一个确认，输入“y”，大概会下载6个安装包，安装完成后需要重启计算机。
