9月3号这天，一天之内FreeBSD竟然发布了三个 Security Advisories，赶紧查看了下，有一个是和icmp6有关的，我的服务器不支持ipv6，另一个是和am64有关，咱的也不是，只有“FreeBSD-SA-08:08.nmount”和我有关系，会产生以下影响：
If the system is configured to allow unprivileged users to mount file
systems, it is possible for a local adversary to exploit this
vulnerability and execute code in the context of the kernel.

没别的说得，迅速patch了下！
