These fixes address vulnerabilities in App Store logging, Bluetooth, command-line utilities, font handling, graphics drivers, PDF handling, Spotlight, and more. Unfortunately, the security update does not include a fix for the Thunderstrike attack, leaving Macs running older operating systems vulnerable (see '[3]Thunderstrike Proof-of-Concept Attack Serious, but Limited,' 9 January 2015). However, the update does includes Safari 6.2.3 for Mountain Lion and Safari 7.1.3 for Mavericks, both of which fix multiple memory corruption issues in WebKit that could allow a malicious Web site to execute code. Security Update 2015-001 is available via Software Update or via direct download from Apple's Support Downloads Web site. (Free. For [4]10.8 Mountain Lion, 177.4 MB; for [5]10.9 Mavericks, 62.3 MB.)
