                   Microsoft Word Font Parsing Vulnerability
                     [Microsoft Security Bulletin MS05-035]
July 12, 2005 19:00 GMT                                           Number P-246
______________________________________________________________________________
PROBLEM:       A vulnerability was discovered in Microsoft Word font parsing 
               code. This bulletin replaces Security Update MS05-023. 
PLATFORM:      Microsoft Office 2000 Software Service Pack 3 
                  Word 2000 
               Microsoft Office XP Software Service Pack 3 
                  Word 2002 Microsoft 
               Works Suites: 
                  Microsoft Works Suite 2000 
                  Microsoft Works Suite 2001 
                  Microsoft Works Suite 2002 Microsoft Works Suite 2003 
                  Microsoft Works Suite 2004 
DAMAGE:        A remote attacker may be able to execute code on a victims 
               machine. The vulnerability stems from an unchecked buffer in 
               the software used by Microsoft Word to process or parse fonts. 
SOLUTION:      Apply the security updates. 
______________________________________________________________________________
VULNERABILITY  The risk is MEDIUM. An attacker could exploit the vulnerability 
ASSESSMENT:    by sending a specially-crafted document to the user and by 
               persuading the user to open the file. If the user opened the 
               file, the affected software could fail and could allow the 
               attacker to execute arbitrary code.

Software Update Services:
By using Microsoft Software Update Services (SUS), administrators can quickly and reliably deploy the latest 
critical updates and security updates to Windows 2000 and Windows Server 2003-based servers, and to desktop 
systems that are running Windows 2000 Professional or Windows XP Professional.
For more information about how to deploy this security update with Software Update Services, visit the 
Software Update Services Web site.
Systems Management Server:
Microsoft Systems Management Server (SMS) delivers a highly-configurable enterprise solution for managing 
updates. By using SMS, administrators can identify Windows-based systems that require security updates and 
to perform controlled deployment of these updates throughout the enterprise with minimal disruption to end 
users. For more information about how administrators can use SMS 2003 to deploy security updates, visit the 
SMS 2003 Security Patch Management Web site. SMS 2.0 users can also use Software Updates Service Feature Pack 
to help deploy security updates. For information about SMS, visit the SMS Web site.
Note SMS uses the Microsoft Baseline Security Analyzer and the Microsoft Office Detection Tool to 
provide broad support for security bulletin update detection and deployment. Some software updates may not 
be detected by these tools. Administrators can use the inventory capabilities of the SMS in these cases to 
target updates to specific systems. For more information about this procedure, see the following Web site. 
Some security updates require administrative rights following a restart of the system. Administrators can 
use the Elevated Rights Deployment Tool (available in the SMS 2003 Administration Feature Pack and in the 
SMS 2.0 Administration Feature Pack) to install these updates.

General Information
	
Executive Summary
Executive Summary:
This update resolves a newly-discovered, privately-reported vulnerability. The 
vulnerability is documented in the Vulnerability Details section of this 
bulletin.
If a user is logged on with administrative user rights, an attacker who 
successfully exploited this vulnerability could take complete control of an 
affected system. An attacker could then install programs; view, change, or 
delete data; or create new accounts with full user rights. Users whose accounts 
are configured to have fewer user rights on the system could be less impacted 
than users who operate with administrative user rights.
We recommend that customers apply the update at the earliest opportunity.
