SYMPTOMS
Microsoft has released updates for Excel 2002, Excel 2000, and Word 2002 that apply all previously released updates for these products. Additionally, these updates remove four newly discovered vulnerabilities:


 * An Excel macro execution vulnerability that relates to how inline macros that are associated with objects are handled. Because of this vulnerability, macros can be executed and bypass the Macro Security Model when the user clicks on an object in a workbook.
 * An Excel macro execution vulnerability that relates to how macros are handled in workbooks when those workbooks are opened through a hyperlink on a drawing shape. Macros in a workbook that is opened this way can run automatically.
 * An HTML script execution vulnerability that may occur if an Excel workbook with an XSL style sheet that contains HTML scripting is opened. The script in the XSL style sheet could be run in the local computer zone.
 * A new variant of the &quot;Word Mail Merge&quot; vulnerability that was first addressed in MS00-071. This new variant could enable an attacker's macro code to run automatically if the user had Microsoft Access present on the system and chose to open a mail merge document that had been saved in HTML format.

Mitigating Factors

Excel Inline Macros Vulnerability:


 * A successful attack that exploits this vulnerability would require that the user accept and open a workbook from an attacker.
 * Additionally, the user would have to click an object in the workbook.
 * There is no way for an attack that exploits this vulnerability to be automated.

Hyperlinked Excel Workbook Macro Bypass:


 * A successful attempt to exploit this vulnerability would require that the user accept and open an attacker's workbook.
 * Additionally, the user would have to click a drawing shape that contains a hyperlink.
 * An attacker's destination workbook would have to be accessible to the user, either on the local computer or an accessible network location.

Excel XSL Style Sheet Script Execution:


 * A user would have to accept and open an attacker's workbook to exploit this vulnerability.
 * Additionally, the user would have to acknowledge a security warning by selecting the non-default option.

Variant of MS00-071, Word Mail Merge Vulnerability:
 * The Word mail merge document would have to be saved in HTML format. Because Word is not the default handler for HTML applications, the user would have to choose to open the document in Word, or acknowledge a security warning.
 * A successful attack requires that Microsoft Access be installed locally.
 * The attacker's data source has to be accessible to the user across a network.
