Would it help to add a disabled_functions list in php.ini? Unless
these functions are needed by Mozdev internal scripts, disabling these
might help:
* system
* exec
* shell_exec
* proc_open
* passthru
* mysql_list_dbs
* dl
* leak (I'm not sure if this is still available in PHP)
These could also be set for greater security (if needed):
* openlog
* syslog
* symlink
* link
* apache_child_terminate
* apache_note
* apache_getenv
* apache_setenv
* virtual
This setting can only be set in php.ini, not httpd.conf or .htaccess or
ini_set(). More info:
http://php.net/manual/en/ini.core.php#ini.disable-functions
There may be other php.ini settings that could be set (like
open_basedir:
http://www.php.net/manual/en/ini.core.php#ini.open-basedir) for greater
security.

P.S. PHP is still disabled for the mp4downloader project. I sent an
email to the sysadmin list, but nothing has changed yet. I don't use PHP
much on this site except to redirect users to Drupal (pretty important,
since most people go to mp4downloader.mozdev.org instead of
mp4downloader.mozdev.org/drupal) and to handle changelog access from
testing versions of my add-on (not having PHP is really messing this up,
but it isn't too important because it is just a testing version).
P.S. (again): I can still run PHP code in local.conf, even though PHP is
disabled in my project. I guess this is necessary for certain settings
and stuff, but it also opens up a security hole.
