Apple has reposted Security Update 2007-005, initially released on May 24th.
Apple gives no explanation for the reposting, but simply re-interates the initial security update's purpose.
From Apple's detailed information on the update:
Security Update 2007-005 v1.1 was released to remove a configuration file that prevented the BIND service from automatically starting after applying the security update. The BIND service is not enabled on default configurations, and is mainly used with a Server system. For systems using BIND which applied Security Update 2007-005, manually re-enabling the BIND service will correct the issue. Security Update 2007-005 v1.1 made no changes to the security content of Security Update 2007-005. Systems that have applied Security Update 2007-005 do not need to apply Security Update 2007-005 v1.1.
The new version is available to applicable users via Software Update, or via Apple's Support Website.
Apple had to update its last security update (2005-004) to v1.1 after the initial update introduced some bugs into specific versions of Mac OS X.
