Microsoft has released Microsoft Office 2004 for Mac 11.3.6 Update, which addresses vulnerabilities in Excel and fixes a bug in Entourage. In Excel, an attacker could "overwrite the contents of your computer's memory with malicious code," according to Microsoft. The Entourage issue concerns data loss when using Microsoft Exchange public folders. Additionally, the Japanese postal code dictionary has been updated. The update, which can be applied most easily via the Microsoft AutoUpdate utility, is a 15.4 MB download and requires the Microsoft Office 2004 for Mac 11.3.5 Update to have been applied previously.
