Yes, but that security update doesn't include this patch. Apple confusingly lists the security updates in 10.10.3 and Security Update 2015-004 together, but not all items apply to 10.9. The very first item listed on the page is this Admin Framework bug, and it's only available for v10.10 to v10.10.2. https://support.apple.com/en-us/HT204659 https://support.apple.com/en-us/HT204659
