服务器的安全升级却是必须的,所以,下面介绍一个yum插件:yum-plugin-security 来进行安全性升级。

1.一般系统默认安装了yum-plugin-security,如果没有,则输入命令安装yum-plugin-security :

$ sudo yum install yum-security

2. 如果是red hat 6,yum-plugin-security现在增加了了一个updateinfo命令。这个命令用来查看可安全更新的软件列表(只查看,不更新),输入下面的命令:

$ sudo yum updateinfo list security

输出:

Loaded plugins: security, versionlock

CVE-2013-1619 security gnutls-2.8.5-10.el6_4.1.x86_64

CVE-2013-1493 security java-1.6.0-openjdk-1:1.6.0.0-1.57.1.11.9.el6_4.x86_64

CVE-2013-0809 security java-1.6.0-openjdk-1:1.6.0.0-1.57.1.11.9.el6_4.x86_64

CVE-2013-0268 security kernel-uek-2.6.39-400.17.2.el6uek.x86_64

CVE-2013-0268 security kernel-uek-firmware-2.6.39-400.17.2.el6uek.noarch

CVE-2012-4929 security openssl-1.0.0-27.el6_4.2.x86_64

CVE-2013-0166 security openssl-1.0.0-27.el6_4.2.x86_64

CVE-2013-0169 security openssl-1.0.0-27.el6_4.2.x86_64

updateinfo list done

对于 red hat 或者 centos 5.x 版本而言,则使用下面的命令来查看可安全更新的软件列表:

$ sudo yum list updates --security

升级需要安全更新的软件包,输入命令:

$ sudo yum update --security

输出如下:

Loaded plugins: security, versionlock
