Apple has released Security Update 2014-002 for 10.8 Mountain Lion, 10.7 Lion, and 10.7 Lion Server, with many of the same security fixes applied to the recently released OS X 10.9.4 Mavericks (see “OS X 10.9.4 Includes Wi-Fi, Wake from Sleep Fixes,” 30 June 2014). All three releases receive updates to the certificate trust policy, as well as fixes for vulnerabilities in maliciously crafted ZIP files, cURL re-using NTLM connections, and the Dock’s handling of messages from applications. The Mountain Lion Security Update also patches vulnerabilities related to a kernel memory issue with graphics drivers, a validation issue in the handling of OpenCL API calls, and array indexing with IOAcceleratorFamily (see the full list of patched vulnerabilities). (All updates are free. For 10.8 Mountain Lion, 139.3 MB; for 10.7 Lion, 134 MB; for 10.7 Lion Server, 184.3 MB.)
Wake On Demand in Snow Leopard
Putting your Mac to sleep saves power, but it also disrupts using your Mac as a file server, among other purposes. Wake on Demand in Snow Leopard works in conjunction with an Apple base station to continue announcing Bonjour services that the sleeping computer offers.
While the requirements for this feature are complex, eligible users can toggle this feature in the Energy Saver preference pane. It's labeled Wake on Network Access for computers that can be roused either via Wi-Fi or Ethernet; Wake on Ethernet Network Access or Wake on AirPort Network Access for wired- or wireless-only machines, respectively. Uncheck the box to disable this feature.
