Microsoft Security Bulletin MS10-079 - Important
Vulnerabilities in Microsoft Word Could Allow Remote Code Execution (2293194)
Version: 1.0
General Information
Executive Summary
This security update resolves eleven privately reported vulnerabilities in
Microsoft Office. The vulnerabilities could allow remote code execution if a
user opens a specially crafted Word file. 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 all supported editions of
Microsoft Word 2002, Microsoft Word 2003, Microsoft Word 2007, Microsoft Word
2010, Microsoft Office 2004 for Mac, and Microsoft Office 2008 for Mac; Open
XML File Format Converter for Mac; and all supported versions of Microsoft
Office Word Viewer and Microsoft Office Compatibility Pack. For more
information, see the subsection, Affected and Non-Affected Software, in this
section.

Vulnerability Information
Word Uninitialized Pointer Vulnerability - CVE-2010-2747
A remote code execution vulnerability exists in the way that Microsoft Word
handles an uninitialized pointer when parsing a specially crafted Word file.
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.
Word Boundary Check Vulnerability - CVE-2010-2748
A remote code execution vulnerability exists in the way that Microsoft Word
handles an improper boundary check when parsing a specially crafted Word file.
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.
Word Index Vulnerability - CVE-2010-2750
A remote code execution vulnerability exists in the way that Microsoft Word
handles index values inside a specially crafted Word file. 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.
Word Stack Overflow Vulnerability - CVE-2010-3214
A remote code execution vulnerability exists in the way that Microsoft Word
handles stack validation when parsing a specially crafted Word file. 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.
Word Return Value Vulnerability - CVE-2010-3215
A remote code execution vulnerability exists in the way that Microsoft Word
handles return values when parsing a specially crafted Word file. 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.
Word Bookmarks Vulnerability - CVE-2010-3216
A remote code execution vulnerability exists in the way that Microsoft Word
handles bookmarks when parsing a specially crafted Word file. 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.
Word Pointer Vulnerability - CVE-2010-3217
A remote code execution vulnerability exists in the way that Microsoft Word
handles pointers when parsing a specially crafted Word file. 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.
Word Heap Overflow Vulnerability - CVE-2010-3218
A remote code execution vulnerability exists in the way that Microsoft Word
handles malformed records inside a specially crafted Word file. 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.
Word Index Parsing Vulnerability - CVE-2010-3219
A remote code execution vulnerability exists in the way that Microsoft Word
handles indexes when parsing a specially crafted Word file. 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.
Word Parsing Vulnerability - CVE-2010-3220
A remote code execution vulnerability exists in the way that Microsoft Word
parses a specially crafted Word file. 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.
Word Parsing Vulnerability - CVE-2010-3221
A remote code execution vulnerability exists in the way that Microsoft Word
