Last night the WordPress folks announced a rushed new release to address what is apparently a pretty major flaw in PHP’s Zend Engine. I unfortunately didn’t have a lot of time to do a thorough upgrade (with backups etc) but I felt that quickly patching was important given that I didn’t have time to find out whether Red Hat had already pushed out a fix for the PHP flaw (there doesn’t seem to be a CVE number for this issue yet, not does it appear in the Red Hat "Days of Risk Report" yet); so I decided to bite the bullet and do the famous "Five second upgrade":
cd path_to_wp_install svn info svn -u apache_user -H svn switch http://svn.automattic.com/wordpress/tags/2.0.7
U wp-includes/version.php U wp-includes/classes.php U wp-includes/functions.php U wp-settings.php U wp-admin/inline-uploading.php U wp-admin/post.php Updated to revision 4734.
svn -u apache_user -H svn up
Fetching external item into 'wp-content/plugins/akismet' U wp-content/plugins/akismet/akismet.php Updated external to revision 7358.
wp-admin/upgrade.php using your web browser.
See the last upgrade notes for a more detailed procedure ("Upgrading from WordPress 2.0.5 to 2.0.6 using Subversion").
