And to not be outdone by Microsoft and Adobe, Apple just released patches for:
iOS 9.2
A total of 50 vulnerabilities (CVE IDs) are addressed. About 10 of them affect WebKit and may lead to arbitrary code execution by visiting a malicious website. There are a large number of additional remote code execution vulnerabilities in various iOS components that are patched.
watchOS 2.1
A lot of overlap with patches released for iOS, but no WebKit issues as watchOS does not include a browser.
XCode 7.2
Updates to git, otools and IDE SCM. The git update fixes a number of vulnerablities that have been known (and fixed) in the open source software for a while.
OS X 10.11.2 (and Security Update 2015-008 for Mavericks and Yosemite)
updates to various open sources packages (libressl, OpenSSH, libxml2 and others). Also improvements to some hardware drivers (e.g. thunderbolt)
Safari 9.0.2
fixes webkit issues for Yosemite, Mavericks and Ell Capitan
tvOS
This affects the just released 4th generation Apple TV and addresses similar vulnerabilities as the new version of iOS.
