OS X El Capitan LogoApple today released Security Update 2016-001 for OS X El Capitan users, introducing important security fixes to the operating system. Apple has also also introduced Security Update 2016-005 for OS X Yosemite users.

The Security Updates are available to all OS X Yosemite and El Capitan users and can be downloaded from the Mac App Store. Apple recommends all users install the update, and a full list of what's fixed can be found in the accompanying support document.

Most security updates are generally built into OS X updates as they are released, with separate security-only updates only being introduced when standard updates to the operating system are not expected. The release of a Security Update for OS X El Capitan suggests we may not see any new versions of the operating system ahead of the launch of macOS Sierra.

Update: Today’s security update fixes a series of critical kernel vulnerabilities that were recently patched in iOS with the release of iOS 9.3.5. On iOS devices, the vulnerabilities were part of a sophisticated jailbreak and malware attack that gave access to all of the functionality of an iPhone or iPad.

Citizen Lab and Lookout, who discovered the vulnerabilities on OS X and iOS, are credited with the fix.

Update 2: There's also a Safari 9.1.3 update to fix vulnerabilities in the Safari browser.

400 MB. Serious ****.
There are three parts to it. If you want to install the El Capitan one manually do it in this order:

Full Bundle Update:
http://swcdn.apple.com/content/downloads/50/35/031-75159/4vr88oyevm1r0p30oz6tx3ygo689whk1f4/FullBundleUpdate.pkg (18.8MB)

Firmware Update:
http://swcdn.apple.com/content/downloads/50/35/031-75159/4vr88oyevm1r0p30oz6tx3ygo689whk1f4/FirmwareUpdate.pkg (130.1MB)

Security Update 2016-001 10.11.6: http://swcdn.apple.com/content/downloads/50/35/031-75159/4vr88oyevm1r0p30oz6tx3ygo689whk1f4/SecUpd2016-001ElCapitan.pkg (265.2MB)

Last one requires a restart.

Here are the Yosemite ones:

Firmware Update http://swcdn.apple.com/content/downloads/31/50/031-74572/d6rg3uuihx9tfvsavc7i4vk1ay6q15hvmt/FirmwareUpdate.pkg (115.5MB)

Security Update 2016-005 10.10.5 http://swcdn.apple.com/content/downloads/31/50/031-74572/d6rg3uuihx9tfvsavc7i4vk1ay6q15hvmt/SecUpd2016-005Yosemite.pkg (352.1MB)

(no Full Bundle Update)

The Yosemite one is actually bigger than the El Capitan one.

Notice that there ISN'T one for mavericks. So that's the end of mavericks as far as security is concerned. But they DID release a new safari for mavericks (and yosemite). Here they are respectively:

I wish Apple would give more details on the "important security fixes" they deploy.

They do in a separate note, always. It will appear here: https://support.apple.com/HT201222.

Be wary if you're using a Mac Pro with the Nvidia web drivers. This broke the current Nvidia driver (346.03.15f02) so no more nice 4K retina display until the Nvidia update is posted.

Here are the release notes for this specific update. [S]https://support.apple.com/en-gb/HT205731[/S]

EDIT:// It would appear these are actually not the correct release notes, why Apple reuses the same name for different security updates is beyond me.
