What Is Suhosin?

~ Suhosin is an advanced protection system for PHP installations. It was designed to protect servers and users from known and unknown flaws in PHP applications and the PHP core.

~ Suhosin is the big brother to the Hardened-PHP patch which adds an extra level of protection to PHP. Installing Suhosin can be a bit confusing so we’ll show you how it can be easily installed on Linux

How To Configure Suhosin In php.ini

The settings below is what works for me on my dev system, but I would advice you to enabled one-by-one and understand the effect it has on your system. This is the best way to adapt those settings to suit your needs.

suhosin.apc_bug_workaround = On
suhosin.session.encrypt = Off
;suhosin.executor.disable_eval=On
suhosin.executor.disable_emodifier=On
suhosin.sql.bailout_on_error=On
suhosin.executor.include.max_traversal=4
suhosin.mail.protect=2
suhosin.memory_limit=128M
suhosin.filter.action=402
suhosin.request.max_array_depth=4096
suhosin.request.max_array_index_length=2048
suhosin.request.max_name_length=2048
suhosin.request.max_value_length=650000
suhosin.request.max_vars=4096
suhosin.post.max_array_depth=8048
suhosin.post.max_array_index_length=1024
suhosin.post.max_name_length=2048
suhosin.post.max_totalname_length=8048
suhosin.post.max_vars=4096
suhosin.upload.max_uploads=100
suhosin.executor.eval.blacklist=”include, include_once, require, require_once, curl_init,fpassthru,file, base64_encode, base64_decode, mail, exec, system, proc_open, leak, syslog, pfsockopen, shell_exec, ini_restore, symlink, stream_socket_server,
proc_nice,popen, proc_get_status, dl,  pcntl_exec, pcntl_fork, pcntl_signal, pcntl_waitpid, pcntl_wexitstatus, pcntl_wifexited, pcntl_wifsignaled, pcntl_wifstopped, pcntl_wstopsig, pcntl_wtermsig, socket_accept, socket_bind, socket_connect, socket_create, socket_create_listen, socket_create_pair,
link, register_shutdown_function, register_tick_function”

NOTE:
=> If you are using systems like wordpress or any other php-systems like forums..etc
Do not enabled ‘suhosin.executor.disable_eval‘, since all those systems use the evil php function eval(). If you enabled it, you wil simply see a blank screen – You have been informed! 😀

–<How about your settings? What works for you?

  2. Hi Chris..
    could you please tell me more about it? How does it make reading difficult?

    I have tried it with several different browsers and it seems fine. And you are the first to actually point out this issue. Would appreciate if you could tell me how you viewed this page, OS (is it via mobile?) and browser that you use.

    Thanks,
    //Wasseem
