Last week was a busy one and not just because of the new iPhone 6 and 6 plus.
OS X 10.9.5 was released and is loaded with security fixes. A few of the noteworthy ones are:
– CoreGraphics, a maliciously crafted PDF could lead to an information disclosure or code execution.
– Intel Graphics Driver, IOAcceleratorFamily and Libnotify, a malicious application may be able to execute arbitrary code with system privileges.
– OpenSSL, just think back on recent OpenSSL issues to get an idea of how critical this is.
Overall, 10.9.5 is a very important update because of the security fixes that are included and is recommended for all Mavericks users. The full list of security fixes included can be found here. 44 total.
OS X 10.9.5 includes the security fixes of Safari 7.0.6. However for the latest Safari version a separate update was released alongside OS X 10.9.5.
Safari 6.2 (Mountain Lion users) and Safari 7.1 (Mavericks users) include some important fixes. The biggest issue that was fixes is one where a man in the middle could intercept user credentials. All the details can be found here.
Apple also released separate security updates for Lion, Lion Server and Mountain Lion, Security Update 2014-004. These updates include some or most of the fixes described above which are included in 10.9.5.
All of these updates can be obtained by running Software Update on your Macs (Apple menu > Software Update or App Store > Updates).

Last but not least, iOS 8. Besides a ton of new features there were a ton of security fixes and improvements as well. If your hardware can handle it (iPhone 5 and up, iPhone 4S not recommended) definitely update your iOS device. The list is too long for me to mention all the fixes so just have a look here.
