Vulnerability Note VU#682820

Microsoft Office routing slip buffer overflow

Overview

Microsoft Office contains a buffer overflow in the parsing of routing slips, which may allow an attacker to execute arbitrary code on a vulnerable system.

I. Description

Routing slips

According to Microsoft Security Bulletin MS06-012:

Microsoft Office applications have the ability to add a "routing slip" to an Office document. Document Routing facilitates the flow of information among a group of users. With Document Routing features as part of a client application, a user can route any type of file to co-workers by attaching it to an e-mail message. It can be sent either to one person at a time or to the group simultaneously. This feature works the same as the File Send option in Office applications, using the same dialogs.

The problem

Microsoft Office contains a buffer overflow in the handling of routing slips.

II. Impact

By convincing a user to open a specially crafted Microsoft Office document, a remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system.

III. Solution

Install an update

Install an update, as specified in Microsoft Security Bulletin MS06-012.

Do not open Microsoft Office documents from untrusted sources

Only open Microsoft Office documents (for example, Word documents, Excel spreadsheets, and PowerPoint presentations) from trusted or known sources. This will reduce the chances of exploitation.
