BUGTRAQ ID: 524
CVE(CAN) ID: CVE-1999-0320
rpc.cmsd（Calendar Manager Service daemon） RPC守护进程是一个用来安排日程的数据库管理器，是CDE桌面环境（Common Desktop Environment）的一个组件，在Solaris等一些Unix系统上是默认运行的。
rpc.cmsd在实现上存在一个缓冲区溢出漏洞远程，远程或本地攻击者可以利用此漏洞以root用户的权限执行任意指令。

建议：
临时解决方法：
如果您不能立刻安装补丁或者升级，NSFOCUS建议您采取以下措施以降低威胁：
* NSFOCUS建议您立刻关闭rpc.cmsd服务。方法是在/etc/inetd.conf中注释掉下列行：
100068/2-5 dgram rpc/udp wait root /usr/dt/bin/rpc.cmsd rpc.cmsd
然后重新启动inetd.
