Apple has released Security Update 2014-002 with security fixes for OS X 10.9 Mavericks, as well as for those still using 10.8 Mountain Lion, 10.7 Lion, and 10.7 Lion Server. According to the release notes, the security update patches a vulnerability with HTTP headers that enabled attackers to obtain Web site credentials, which affected all three versions of OS X. It also fixes a particularly ugly vulnerability to a “triple handshake” attack that could affect both Mavericks and Mountain Lion. However, the bulk of the changes focus on Mavericks, addressing vulnerabilities with CoreServicesUIAgent Web site validation, Heimdal Kerberos authentication, ImageIO’s handling of JPEG images, and a power management issue that could prevent the system from going to sleep and keep the screen unlocked. (All updates are free. For 10.9 Mavericks, 80.5 MB; for 10.8 Mountain Lion, 135.9 MB; for 10.7 Lion, 126.9 MB; for 10.7 Lion Server, 177.2 MB.)
Move the Dock Quickly
You may find it convenient to move the position of the Dock when working in certain programs or with certain files. Rather than choosing a different position from the Dock preferences pane or using a submenu in the Apple menu's Dock submenu, you can move your Dock to a different screen edge merely by Shift-dragging the separator that divides the application and document sections.
