提问三步曲: 提问先看教程/FAQ索引(wdcp,wdcp_v3,一键包)及搜索,会让你更快解决问题
1 提供详细，如系统版本,wdcp版本,软件版本等及错误的详细信息,贴上论坛或截图发论坛
2 做过哪些操作或改动设置等

温馨提示：信息不详,很可能会没人理你！论坛有教程说明的，也可能没人理！因为,你懂的

[已解决] 通知：Linux Glibc库严重安全漏洞修复方案

本帖最后由 cbynd 于 2015-1-30 16:59 编辑

CentOS 和 RedHat 更新方法如下:
1）用户使用root用户, 在系统上执行： # yum clean all; yum update glibc
2) 用户使用root用户, 在系统上执行： # y
3）以上命令执行完成后，查看Glibc版本：# rpm -qa|grep glibc-2.12 （跟右侧对应glibc版本对应的话，说明修复成功）

OS版本更新成功对比：

OS版本	对应Glibc版本
CentOS6.x/redhat6.x	glibc-2.12-1.149.el6_6.5
OS版本: CentOS 6.2 安全版(tlinux)	glibc-2.12-1.149.tl1.5
CentOS5.x/redhat5.x	glibc-2.5-123.el5_11.1

Ubuntu 更新方法如下：
【针对Ubuntu，腾讯云软件仓库已完成同步】

1）用户使用root权限登录系统或使用sudo获取root权限，执行以下命令：
#apt-get update
#apt-get install libc6

2）执行完成以后，查看版本，输出如下表示更新完成：
root@VM-ubuntu:~# dpkg -l|grep libc6

OS版本	对应Glibc版本
Ubuntu12.x	2.15-0ubuntu10.10
Ubuntu14.x	2.19-0ubuntu6
Ubuntu10.x	2.11.1-0ubuntu7.20

及时更新！

回复 1# cbynd
cbynd你好，我是CentOS 6.3 64位的，现用ssh登陆服务器，按你如下方法操作的，
CentOS 和 RedHat  更新方法如下:
1）用户使用root用户, 在系统上执行： # yum clean all; yum update glibc
2) 用户使用root用户, 在系统上执行： # y
3）以上命令执行完成后，查看Glibc版本：# rpm -qa|grep glibc-2.12 （跟右侧对应glibc版本对应的话，说明修复成功）

但是更新后查看Glibc版本情况好象与你描述的不一样，烦请帮忙看看谢谢！详见下：
[root@AY140115162727456ea9Z ~]# rpm -qa|grep glibc-2.12
glibc-2.12-1.149.el6_6.5.x86_64

这个是还没有更新前查看显示的代码：
[root@AY140115162727456ea9Z ~]# rpm -qa|grep glibc-2.12
glibc-2.12-1.107.el6_4.2.x86_64

从更新前和更新后的代码看，不知究竟更新成功没有？帮忙确认下好吗！
以下是在ssh上更新时的完整代码：
