Excellent piece of Microsoft software... Can't even install it on Word 2002 German on WinXP German. The patch says (translated) "did not find the product expected". I then tried the office update site. That fails with an general error, telling me I should review my security settings. Bottom line: nice patch, but can't install... Am I now guilty of lazyness if I do not patch? Anyone else with similar problems? Rainer Gerhards

Microsoft Word supports the use of macros to allow the automation of commonly performed tasks. Since macros are executable code it is possible to misuse them, so Microsoft Word has a security model designed to validate whether a macro should be allowed to execute depending on the level of macro security the user has chosen. A vulnerability exists because it is possible for an attacker to craft a malicious document that will bypass the macro security model. If the document was opened, this flaw could allow a malicious macro embedded in the document to be executed automatically, regardless of the level at which macro security is set. The malicious macro could take the same actions that the user had permissions to carry out, such as adding, changing or deleting data or files, communicating with a web site or formatting the hard drive. The vulnerability could only be exploited by an attacker who persuaded a user to open a malicious document - there is no way for an attacker to force a malicious document to be opened. Mitigating Factors: ==================== - The user must open the malicious document for an attacker to be successful. An attacker cannot force the document to be opened automatically. - The vulnerability cannot be exploited automatically through e- mail. A user must open an attachment sent in e-mail for an e- mail borne attack to be successful. - By default, Outlook 2002 block programmatic access to the Address Book. In addition, Outlook 98 and 2000 block programmatic access to the Outlook Address Book if the Outlook Email Security Update has been installed. Customers who use any of these products would not be at risk of propagating an e-mail borne attack that attempted to exploit this vulnerability. - The vulnerability only affects Microsoft Word - other members of the Office product family are not affected. Risk Rating: ============ -Important Patch Availability: =================== - A patch is available to fix this vulnerability. Please read the Security Bulletins at http://www.microsoft.com/technet/security/bulletin/MS03-035.asp http://www.microsoft.com/security/security_bulletins/MS03-035.asp for information on obtaining this patch.
