rsync

如许多人了解的那样，ftp.freebsdchina.org的服务器挂了，很不幸地，这件事多少也有我一份，在硬件故障之后，我怀疑我尝试修复的最后一次操作给了它致命一击——这台在机房运行了四年之久的机器，终于消失在了机房茫茫闪烁的指示灯中，更为严重的是，我们恐怕永远无法再找到这台机器，因为没有人知道它在机房的确切位置了……

While I believe that proactive security practice is necessary for every consumers, the most conversave ones should argue that even a security update will possibly break compablity.

Now I am in trouble. With rsync 2.5.5 installed on a FreeBSD system, we know that it is possible to overflow its heap, however, shall we patch it, or just let it as-is because it is not exploitable on FreeBSD, unlike Linux’s silly brk(9) implementation?
