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.
