Patch Office X for Network Vulnerability -- Microsoft has released a Network Security Updater for Microsoft Office X that eliminates a network vulnerability made possible by a flaw in the application suite's network-aware anti-piracy mechanism. Office X checks to make sure that every copy running on the network is using a unique product identifier (PID); if an Office application detects a duplicate, it shuts down. As discovered by Marty Schoch, the problem is that the checking code doesn't correctly handle a malformed PID announcement, causing the first Office application launched to crash, with the possible loss of data. So although someone could cause Office applications to crash by sending malformed PID announcements, there is no possibility that data could be created, deleted, or modified. For full details, see Microsoft Security Bulletin MS01-002. [ACE]
Turn Off Filename Extension Warning
In Leopard, Apple fixed an annoying aspect of working with the Finder in Tiger. Previously, if you changed a file's extension, the Finder prompted for confirmation. But since no one has ever accidentally changed a filename extension, Apple thankfully added an option to turn that warning off in the Leopard Finder's preferences. Choose Finder > Preferences, and in the Advanced screen, deselect Show Warning Before Changing an Extension.
