Mac OS X 10.7 < 10.7.4 Multiple Vulnerabilities

This script is Copyright (C) 2012-2013 Tenable Network Security, Inc.


Synopsis :

The remote host is missing a Mac OS X update that fixes several
security issues.

Description :

The remote host is running a version of Mac OS X 10.7 that is older
than version 10.7.4. The newer version contains numerous security-
related fixes for the following components :

- Login Window
- Bluetooth
- curl
- HFS
- Kernel
- libarchive
- libsecurity
- libxml
- LoginUIFramework
- PHP
- Quartz Composer
- QuickTime
- Ruby
- Security Framework
- Time Machine
- X11

Note that this update addresses the recent FileVault password
vulnerability, in which user passwords were logged in clear text to a
system-wide debug log if the legacy version of FileVault is used to
encrypt user directories after a system upgrade to Lion. Since the
patch only limits further exposure, though, we recommend that all
users on the system change their passwords if user folders were
encrypted using the legacy version of FileVault prior to and after an
upgrade to OS X 10.7.
