Apple has released Safari 7.0.6 for users of OS X 10.9 Mavericks and Safari 6.1.6 for users of 10.8 Mountain Lion and 10.7 Lion. Both updates improve memory handling to fix multiple WebKit memory corruption issues that could lead to unexpected application termination or arbitrary code execution if visiting a maliciously crafted Web site. (Seven Common Vulnerabilities and Exposures IDs, or CVE-IDs, are listed in the security note.) The two releases are available only through Software Update. (Free, 10.9+/10.7–10.8)
Untrash the Trash
Feeling trasher's remorse? On Snow Leopard, you can open the Trash (click the Trash icon in the Dock) and "untrash" individual items there. Select one or more trashed items (files and folders) and choose File > Put Back. This returns the items to where they were when you originally put them in the trash. The keyboard shortcut is Command-Delete - the same as the shortcut for trashing an item in the first place, since in deleting something from the trash you are untrashing it.
