Apple yesterday released the latest version of its operating system, OS X 10.10 Yosemite. As usual, the new version of the operating system does include a number of security related bug fixes, and Apple released these fixes for older versions of OS X today.

This update, Security Update 2014-005 is available for versions of OS X back to 10.8.5 (Mountain Lion). 

Among the long list of fixes, here a couple of highlights:

Apple doesn't turn off SSLv3 in this release, but restricts it to non-CBC ciphers, limiting its exposure to attacks like POODLE and BEAST. The list of trusted certificate authorities has also been updates [2]

802.1x no longer supports LEAP by default due to weaknesses in this authentication method.

The bash fix, that was released as a standalone fix earlier to counter "Shellshock", is included in this update.

An arbitrary code execution vulnerability in CUPS was fixed. (CVE-2014-3537)

And a quick note about OS 10.10 Yosemite:

After installing it, all security relevant settings I checked where untouched (good!). Among security relevant software, GPGMail will not work with Yosemite yet, but according to the developers, a fix is in the work and may be release in a few weeks, but GPGMail may no longer be free. If you rely on software that you compiled with MacPorts: Wait for the release of XCode 6.1, as it is required to recompile the software for OS X 10.10. In general, it is adviced that you FIRST update all your software and then upgrade to Yosemite. Little Snitch, another popular piece of security software for OS X, works well with Yosemite, but I recommend you turn off the network filter during the upgrade (it works with it enabled, but you need to approve a lot of new connections from new software).
