------
RedHat已经为此发布了一个安全公告（RHSA-2002:210-06）以及相应补丁:
RHSA-2002:210-06：New kernel 2.2 packages fix local vulnerabilities
链接：https://www.redhat.com/support/errata/RHSA-2002-210.html
在采用这个更新之前，确定所有以前发行的勘误表中相关补丁已经采用。
手工升级内核过程文档可从如下地址获得：
http://www.redhat.com/support/docs/howto/kernel-upgrade/
在升级内核之前请仔细阅读你结构相关的操作指南。
用户也可以通过如下RedHat升级代码通过网络进行升级：
up2date
这个命令将会启动交互进程安装升级相关RPM。
