Updates: MySQL 5.1.72, PHP 5.4.21, PHP 5.5.5 (completed)

We’ve updated MySQL from version 5.1.66 to version 5.1.72. This upgrade was necessary for security reasons.

We’ve also updated the PHP 5.4 series from 5.4.20 to 5.4.21, and the PHP 5.5 series from 5.5.4 to 5.5.5, to fix several bugs.

These updates should be invisible to customers, but as always, don’t hesitate to contact us if you have any questions or concerns.

Technical details of the CVE-2013-4365 mod_fcgid bug

This post is technical, and intended for programmers and security experts — it doesn’t affect our customers.

A few weeks back, one of our hosting customers had a PHP script that would constantly crash an Apache Web server process. We spent a while tracking down the cause, and eventually found a bug in the excellent Apache mod_fcgid FastCGI software that was causing it.

WordPress 3.6.1

WordPress 3.6.1 was recently released, and as always, we’ve updated our WordPress one-click installer to automatically install the latest version for new WordPress sites.

If you’ve previously installed WordPress, you should update it from within your WordPress Dashboard.

The new version of WordPress is described as a security release that prevents “hackers” from modifying your site if you use “a popular plugin“, whose name has not yet been revealed so that everyone has a chance to upgrade first. While we may be able to add additional protection against this vulnerability when the details are revealed, updating now guarantees your site will stay protected.

Protection against a critical Joomla file upload security bug

There’s been a lot of discussion recently about a critical Joomla security bug that allows “hackers” to upload malicious PHP script files to Joomla sites, then run them. This would allow hackers to use your site to send spam, or to replace any file on your Web site.

Although our customers running Joomla should always upgrade to the latest versions when available, we’ve also put rules in place to protect against this vulnerability.

WordPress login rate limiting (again)

We’ve talked before about WordPress login rate limiting. Attempts to guess WordPress administrator passwords are an ongoing problem, getting worse all the time.

The average WordPress site we host has received tens of thousands of malicious login attempts this month, with hundreds of thousands of different IP addresses being used in the attacks. We try to block the IP addresses that are responsible, but the ever increasing number of addresses means we can’t block all of them — an individual address often attempts a login only once a day for a given site. We need to adopt other tactics.
