Apple releases OS 10.8.4

Apple released the next update for OS X, 10.8.4. Eventually, we should learn more about the security content of the update, but at this point, the security page has not been updated yet [1]. 

However, Apple did distribute a list of patched vulnerabilities via e-mail (thanks Dave for sharing). The update fixes a total of 33 vulnerabilities. Here are some of the highlights:

Typo above: CVE-2013-5519 here really means CVE-2012-5519; it was known publicly and the vendor notified almost 7 months ago. A user who could configure printers could also read/overwrite any file on that system.

I'd never seen a detailed list before of the vulnerabilities that are patched in OS X. The attack surface is so broad here, from network services to multimedia codecs. People don't use these devices for anything important, do they? Like accessing their email, Internet banking, software development...

Safari 6.0.5 security content -

The combo updater download is about 900 meg. It took about 20 minutes to install on a 2012 MacBook Pro running 10.8.3.

p.s. Steven, the attack surface doesn't seem any broader than the average Windows or Linux update...

Looks like there's also a Security Update 2013-002 for both Lion and Snow Leopard. Can anyone explain Apple's patch release policies to me; thought they only support the 2 most current versions. Did that end w/ their Java debacle?

Re: Apple software update lifecycle

Actually, its a -2 methodology. They support the existing OS version currently being installed and the two previous. So that would mean everything back to 10.6.x (snowleopard) is still being supported. When they go to a 10.9, then you will effectively only get updates for 10.7 and later.
