On the other hand, until Apple patches these flaws, staying on Mountain Lion and older OS X versions is a bit more risky.

On the one hand, it’s good that Apple has not changed its update policy and plans to patch vulnerabilities in older OS X versions. The security implications of Apple no longer patching vulnerabilities in older OS X versions were immediately clear: users that don’t upgrade are necessarily running an operating system with many disclosed, yet unpatched vulnerabilities, which opens them up to potential attack. Since first mentioning that older OS X versions went unpatched, Larry Seltzer has updated his article after an Apple spokesperson told ZDNet, “ company has not changed its update policy,” but clarified, “some older OS X versions go unpatched for architectural reasons.” However, Larry noted that Apple declined to comment on the request for additional information about their security update policy or for when the most recently disclosed vulnerabilities would be patched in Mountain Lion. Is Apple intentionally not offering security updates for versions of OS X older than the current one, due to a change in their update policy? Released for Mac OS X 10.6.8 and later, Apple’s OS X Mavericks 10.9 upgrade patches 48 vulnerabilities (CVEs), but as pointed out by Larry Seltzer at ZDNet, something is missing: Older OS X versions were left unpatched. Last week, Apple released a plethora of security updates with OS X Mavericks 10.9 and other software, including patching iOS vulnerabilities with iOS 7.0.3 and fixing a number of flaws in its web browser with Safari 6.1.
