요즘 php injection 보안버그 때문에 말이 많습니다. phpbb의 경우에는 worm 같이 그 외에 많이 사용되는 zeroboard, korweblog, jsboard, gnuboard 등등.. 대부분의 injection 보안버그는 대부분 system 관련 함수를 사용하여 spam 을 보내거나 index page 를 변고 하거나, 대부분의 관리자들이 간과하는 local expolit 을 실행해서 root shell 을 얻는데 많이 이용됩니다. 이 경우 가장 많이 사용되는 것이 system 함수이며, 그 외에 exec, passthru, popen 등의 함수가 있습니다. php.ini 에서 이 함수들을 막아놓는 것도 한방법이지만 그렇다고 막으면 원성이 자자합니다. 그러던 중에, safe mode 에서 사용되는 safe_mode_exec_dir 을 safe mode 가 아닐 경우에도 사용을 할 수 있으면, system 관련 함수를 제어하는데 아주 좋을 것 같아서, php 4.3.10 을 기준으로 safe mode 가 아닐때도 사용이 가능하도록 패치를 해 보았습니다. 대략 safe mode 일 경우, php 는 meta charactor 를 escape 시

The fdisk won't create partitions larger than 2 TB. This is fine for desktop and laptop users, but on server you need a large partition. For example, you cannot create 3TB or 4TB partition size (RAID based) using the fdisk command. It will not allow you to create a partition that is greater than 2TB.
