Three updates for Microsoft Office v.X for the Mac have been released.

Microsoft Office v.X Combined Updater 10.0.3 includes Entourage X Hotmail Update, Network Security Update, and the URL Security Updater.

Entourage X Hotmail Update allows Entourage X to connect to MSN Hotmail servers. This feature has been updated using the latest, most secure technologies, Microsoft claims.

No fake IDs Network Security Update runs Office v.X and its stand-alone programs more securely on a network. Office v.X contains a network-aware, anti-piracy mechanism that detects multiple copies of Office using the same product identifier (PID) running on a local network. This feature, called the Network Product Identification Checker, announces Office’s own unique product ID, and listens for other announcements at regular intervals. If a duplicate PID is detected, Office shuts down. This update fixes a security flaw in the Network PID Checker.

URL breaks loose URL Security Update addresses security vulnerabilities. Previously, addresses could be hacked to run malicious code on a Mac. URL Security Update eliminates previously released security-vulnerabilities affecting Internet Explorer 5.1 for Mac and Office v.X. It also eliminates two newly discovered problems. The first is a buffer-overrun vulnerability associated with the handling of HTML. A successful buffer-overrun attack against Internet Explorer would cause the program to fail, or cause code of the attacker’s choice to run as if it were the user.

The second is a vulnerability that allows local AppleScripts to be invoked by a Web page. In this situation, AppleScripts would run as if launched by the user.

The updates apply to Office v.X, Word X, Excel X, PowerPoint X, and Entourage X.

IE security boost Microsoft has also updated its OS X-compatible Internet Explorer browser. Internet Explorer X 5.1.4 is only available through OS X’s Software Update feature. It resolves security vulnerabilities in previous versions of Internet Explorer 5, including weaknesses that could have caused Internet Explorer to stop responding or caused a memory problem that compromised the security of the computer.
