The Office 2008 for Mac 12.0.1 Update contains several changes that improve security, stability, and performance. These changes include fixes for users of Mac OS X 10.5 Leopard, and include fixes for vulnerabilities that an attacker can use to overwrite the contents of a computer’s memory by using malicious code.
This update fixes an issue that could give a local user who does not have administrator permissions access Office 2008 program files. This issue occurs when the non-administrative user account was assigned User ID 502. This issue affects only computers that have more than one local user account, and primarily affects environments, such as public computer labs and workplace networks, where access to program files is restricted.
The update can be obtained directly from Microsoft.
