Providing the perl stack as RPMs

The information in this post is about a project in motion. The final delivery may differ from what is discussed here, especially as we consider the feedback you have.

Update: the changes discussed in this article are delayed until a future version of cPanel & WHM. They are not in version 11.34.

Our last article discussed changing from compile-on-demand to delivery of pre-compiled binary packages, using the RPM format. A primary driver behind this was our use of perl. To deliver perl via pre-built RPM packages required a number of changes to the product.

Switching from compile-on-demand to binary packages

For many years installing and using cPanel & WHM has involved compiling software on-demand. Want Apache and PHP? Run /scripts/easyapache, which builds those and all dependencies from source. Want perl installed? Download and run the perl installer from, which installs perl from source. While compiling from source has its benefits, it also has its drawbacks.

Pending Removal of Atmail open plugin

With cPanel & WHM 11.28 the ability for server owners to provide custom webmail applications was introduced. To demonstrate this feature we introduced the Atmail Open plugin.

If you have not already, please verify your version of the plugin has been updated. The Atmail Open 1.0.5 release addresses some security issues. Continue reading

cPanel Protects Against PHP Vulnerability

cPanel & WHM servers using the default cPanel PHP CGI configuration are not vulnerable to the command line switch vulnerability.

A recently disclosed flaw in PHP’s CGI implementation allows malicious users to remotely view and execute source code. The exploit was documented by the Eindbazen team and documented as CVE-2012-1823.

cPanel & WHM servers are not affected by this, thanks in part to a wrapper script used by cPanel & WHM when Apache is configured to use CGI for the PHP handler. This wrapper script does not pass through any command line options.

Server administrators are encouraged to verify their PHP configuration.

When configured to use CGI or FCGI, cPanel & WHM instructs Apache to use the following wrapper script /usr/local/cpanel/cgi-sys/php5 or /usr/local/cpanel/cgi-sys/php4 (The number after “php” is based upon the current major version of PHP.) The unmodified version of the wrapper script looks like the following:

The $binary placeholder will contain /usr/bin/php or /usr/php4/bin/php By default, no command line parameters are included.

# If you customize the contents of this wrapper script, place
# a copy at /var/cpanel/conf/apache/wrappers/php$php_version
# so that it will be reinstalled when Apache is updated or the
# PHP handler configuration is changed
exec $binary

cPanel releases EasyApache 3.12

EasyApache 3.12 improves CloudLinux’s modhostinglimits, modmono compatibility on CentOS 4, and mod_ruid2 to suPHP support

We are excited to announce the release of EasyApache 3.12. The latest version provides numerous updates.

  • CloudLinux’s mod_hostinglimits has been updated to 0.9-5. This will impact all of those who use CloudLinux.
  • The issues caused by the glib2 update when building mod_mono on CentOS4 have been resolved.
  • Switching between mod_ruid2+DSO to suPHP will no longer cause permission errors that can cause PHP sites to no longer function.
  • PHP will now use the system time zone database rather than the one built into PHP, which will ensure PHP applications receive timely updates to time zone changes

We strongly recommend that all server administrators rebuild their EasyApache profile immediately.

To rebuild the EasyApache profile:

  1. Log in to WHM as the root user.
  2. Click on the EasyApache (Apache Update) link in the left menu.
  3. If you wish to keep the same configuration, simply click Build Profile.
