Keeping up with our promise of providing you with the safest hosting environment, we have to make a few changes to our PHP installation on our Linux Hosting Servers. We will be disabling a few PHP functions that allow users to execute system commands on the servers that disclose system information in a shared hosting environment. These functions are sparingly required by clients and are more of a security threat to your websites.
The functions that will be deprecated are:
system, shell_exec, exec, passthru, php_uname, popen, posix_kill, posix_mkfifo, posix_setpgid, posix_setsid, posix_setuid, posix_setgid, posix_uname, proc_close, proc_nice, proc_open, proc_terminate
We will be making these changes on Friday, 27th of November, 2009. If you are using these functions in your PHP scripts, you will have to inform your customers accordingly about these changes.
Your co-operation is highly appreciated.
