Perl software updated to fix security bug

We’ve updated our servers with a Perl security bug fix. This won’t affect most customers, but read on if you know you use Perl scripts on your site.

This is an interesting change in Perl, because the original bug was that Perl successfully ran some incorrectly written scripts that it should have refused to run for security reasons. Due to the bug fix, it’s possible (though unlikely) for Perl scripts to start displaying an error message about an “insecure dependency” or “tainted data”, even though they previously appeared to run normally.

If you use Perl scripts on your site, you should test them to be sure this update hasn’t affected anything. If you find a problem, let us know and we can help.
