Microsoft Security Bulletin MS10-105 - Important
Vulnerabilities in Microsoft Office Graphics Filters Could Allow for Remote
Code Execution (968095)
Version: 1.0
General Information
Executive Summary
This security update resolves seven privately reported vulnerabilities in
Microsoft Office. The vulnerabilities could allow remote code execution if a
user viewed a specially crafted image file using Microsoft Office. An
attacker who successfully exploited any of these vulnerabilities could gain
the same user rights as the local user. 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.
This security update is rated Important for Microsoft Works 9, Microsoft
Office Converter Pack, and supported editions of Microsoft Office XP and
Microsoft Office 2003. For more information, see the subsection, Affected
and Non-Affected Software, in this section.
The update addresses the vulnerabilities by modifying the way that Microsoft
Office parses certain image formats and validates data when rendering images.
For more information about the vulnerability, see the Frequently Asked
Questions (FAQ) subsection for the specific vulnerability entry under the
next section, Vulnerability Information.

Vulnerability Information
CGM Image Converter Buffer Overrun Vulnerability - CVE-2010-3945
A remote code execution vulnerability exists in the way that Microsoft
Office allocates buffer size when handling CGM image files. The
vulnerability could allow remote code execution if a user opens an
Office document containing a specially crafted CGM image. 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.
PICT Image Converter Integer Overflow Vulnerability - CVE-2010-3946
A remote code execution vulnerability exists in the way that Microsoft
Office allocates buffer size when handling PICT image files. The
vulnerability could allow remote code execution if a user opens an
Office document containing a specially crafted PICT image. 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.
TIFF Image Converter Heap Overflow Vulnerability - CVE-2010-3947
A remote code execution vulnerability exists in the way that Microsoft
Office parses specially crafted TIFF image files. The vulnerability could
allow remote code execution if a user opens an Office document containing a
specially crafted TIFF image. 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.
TIFF Image Converter Buffer Overflow Vulnerability - CVE-2010-3949
A remote code execution vulnerability exists in the way that Microsoft
Office parses specially crafted TIFF image files. The vulnerability could
allow remote code execution if a user opens an Office document containing a
specially crafted TIFF image. 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.
TIFF Image Converter Memory Corruption Vulnerability - CVE-2010-3950
A remote code execution vulnerability exists in the way that Microsoft
Office parses specially crafted TIFF image files. The vulnerability could
allow remote code execution if a user opens an Office document containing a
specially crafted TIFF image. 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.
FlashPix Image Converter Buffer Overflow Vulnerability - CVE-2010-3951
A remote code execution vulnerability exists in the way that Microsoft
Office parses specially crafted FlashPix image files. The vulnerability
could allow remote code execution if a user opens an Office document
containing a specially crafted FlashPix image. 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.
FlashPix Image Converter Heap Corruption Vulnerability - CVE-2010-3952
A remote code execution vulnerability exists in the way that Microsoft
Office parses specially crafted FlashPix image files. The vulnerability
could allow remote code execution if a user opens an Office document
containing a specially crafted FlashPix image. 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.
