PROTECT THE BEACH Mac OS
This document describes the security content of OS X Lion v10.7.3 and Security Update 2012-001, which can be downloaded and installed via Software Update preferences, or from Apple Downloads.
For the protection of our customers, Apple does not disclose, discuss, or confirm security issues until a full investigation has occurred and any necessary patches or releases are available. To learn more about Apple Product Security, see the Apple Product Security website.
- Aware of the problem, Apple eventually replaced the classic Mac operating system with the new Mac OS X, which came with built-in malware security measures. For instance: Quarantine, introduced in 2007, alerts users if they try to open applications downloaded from the Internet. It acts as a reminder, in effect prompting users to think twice.
- Surprisingly, you can also password protect documents in Excel, Word, and PowerPoint in the Microsoft Office for Mac suite. It's more expensive than iWork, but again, there's a 30 day free trial.
For information about the Apple Product Security PGP Key, see 'How to use the Apple Product Security PGP Key.'
Where possible, CVE IDs are used to reference the vulnerabilities for further information.
Worksheet protection is a two-step process: the first step is to unlock cells that others can edit, and then you can protect the worksheet with or without a password. Open the sheet that you want to protect. Click Review Protect Sheet. In the Allow users of this sheet to list, select the elements that you want users to be able to change.

OS X Lion v10.7.3 and Security Update 2012-001
Address Book
Available for: OS X Lion v10.7 to v10.7.2, OS X Lion Server v10.7 to v10.7.2
Impact: An attacker in a privileged network position may intercept CardDAV data
Description: Address Book supports Secure Sockets Layer (SSL) for accessing CardDAV. A downgrade issue caused Address Book to attempt an unencrypted connection if an encrypted connection failed. An attacker in a privileged network position could abuse this behavior to intercept CardDAV data. This issue is addressed by not downgrading to an unencrypted connection without user approval.
