Apple has updated Security Update 2007-009 to v1.1, available in 10.4.11 PPC and Universal and 10.5.1 Universal flavors.
According to Apple's documentation, the new version does not affect the security content of the original update, but addresses an issue that may cause Safari to unexpectedly quit when browsing to certain websites.
Apple initially released Security Update 2007-009 earlier this week, which included a host of security updates for both 10.4.11 and 10.5.1.
