verwendet Word-Engine zum Bearbeiten von E-Mails), um beliebigen Code
mit den Rechten des Benutzers auszufuehren.

CVE-2010-3334 – Schwachstelle in Microsoft Office beim Bearbeiten von
Art-Datensaetzen

In Microsoft Office kann es beim Bearbeiten von Art-Datensaetzen in
Office-Dokumenten, die einen msofbtSp-Record beinhalten, zu einer
Verletzung von Speicherbereichen kommen. Ein entfernter Angreifer kann
diese Schwachstelle mittels eines speziell konstruierten
Office-Dokuments ausnutzen, um beliebigen Code mit den Rechten des
Benutzers auszufuehren.

CVE-2010-3336 – Schwachstelle in Microsoft Office beim Bearbeiten von
SPID-Daten

In Microsoft Office existiert eine Schwachstelle beim Bearbeiten von
SPID-Daten in Office-Dokumenten, die zu der Verletzung von

Microsoft Security Bulletin MS10-087 – Critical

Vulnerabilities in Microsoft Office Could Allow Remote Code Execution (2423930)

Version: 1.0

General Information

Executive Summary

This security update resolves one publicly disclosed vulnerability and four
privately reported vulnerabilities in Microsoft Office. The most severe
vulnerability could allow remote code execution if a user opens or previews a
specially crafted RTF e-mail message. 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 Critical for all supported editions of Microsoft
Office 2007 and Microsoft Office 2010. This security update is also rated
Important for all supported editions of Microsoft Office XP, Microsoft Office
2003, Microsoft Office 2004 for Mac, Microsoft Office 2008 for Mac, and
Microsoft Office for Mac 2011; and Open XML File Format Converter for Mac.
For more information, see the subsection, Affected and Non-Affected Software,
in this section.

formatted data. 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.

Office Art Drawing Records Vulnerability – CVE-2010-3334

A remote code execution vulnerability exists in the way that Microsoft
Office software parses specially crafted Office files. 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.

Drawing Exception Handling Vulnerability – CVE-2010-3335

A remote code execution vulnerability exists in the way that Microsoft
Office software parses specially crafted Office files. An attacker who
successfully exploited this vulnerability could take complete control of
an affected system. An attacker could then install programs; view, change,
