Liebe Kolleginnen und Kollegen,
soeben erreichte uns nachfolgende Warnung des Microsoft Product Security
Notification Service. Wir geben diese Informationen unveraendert an Sie
weiter.
CVE-2009-1547 - Schwachstelle im Internet Explorer bei der Bearbeitung
von HTML-Responses
Im Internet Explorer existiert eine Schwachstelle bei der Bearbeitung
von Header-Informationen aus Datenstroemen (data stream header). Davon
betroffen ist die Implementierung des "Content-Encoding:deflate"
Headers. Ein entfernter Angreifer kann diese Schwachstelle mittels
einer speziell konstruierten Web-Seite ausnutzen, um beliebige Befehle
mit den Rechten des Benutzers auszufuehren.
CVE-2009-2530 / CVE-2009-2531 - Schwachstellen im Internet Explorer beim
Zugriff auf Objekte
Aufgrund einer Schwachstelle im Internet Explorer beim Aufruf des
Copy-Constructors fuer bestimmte DOM-Objekte wird ein noch verwendeter
Speicherbereich fehlerhafterweise bereits freigegeben. Ein entfernter
Angreifer kann diese Schwachstelle mittels einer speziell
konstruierten Web-Seite ausnutzen, um beliebige Befehle mit den
Rechten des Benutzers auszufuehren.
CVE-2009-2529 - Schwachstelle im Internet Explorer bei der Bearbeitung
von HTML-Komponenten
Eine HTML-Komponente ist praktisch ein Objekt, das eine HTML-Seite mit
Methoden zum Zugriff darauf buendelt. Die Komponenten unterstuetzen
beispielsweise den dynamischen Aufbau und Aenderungen von HTML-Seiten.
Im Internet Explorer existiert eine Schwachstelle bei der Validierung
von Argumenten durch HTML-Komponenten. Ein entfernter Angreifer kann
diese Schwachstelle mittels einer speziell konstruierten Web-Seite
ausnutzen, um beliebige Befehle mit den Rechten des Benutzers
auszufuehren.
Betroffen sind die folgenden Software Pakete und Plattformen:
Internet Explorer 5.01
Internet Explorer 6

Microsoft Security Bulletin MS09-054 - Critical
Cumulative Security Update for Internet Explorer (974455)
Published: October 13, 2009
Version: 1.0
General Information
Executive Summary
This security update resolves three privately reported vulnerabilities and
one publicly disclosed vulnerability in Internet Explorer. The
vulnerabilities could allow remote code execution if a user views a specially
crafted Web page using Internet Explorer. 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 releases of Internet
Explorer: Internet Explorer 5.01, Internet Explorer 6, Internet Explorer 6
Service Pack 1, Internet Explorer 7, and Internet Explorer 8. For more
information, see the subsection, Affected and Non-Affected Software, in this
section.
The security update addresses these vulnerabilities by modifying the way that
Internet Explorer processes data stream headers, validates arguments, and
handles objects in memory.
Recommendation. The majority of customers have automatic updating enabled and
will not need to take any action because this security update will be
downloaded and installed automatically. Customers who have not enabled
automatic updating need to check for updates and install this update
manually. For information about specific configuration options in automatic
updating, see Microsoft Knowledge Base Article 294871.
For administrators and enterprise installations, or end users who want to
install this security update manually, Microsoft recommends that customers
apply the update immediately using update management software, or by checking
for updates using the Microsoft Update service.

this bulletin.

Vulnerability Information
Data Stream Header Corruption Vulnerability - CVE-2009-1547
A remote code execution vulnerability exists in the way that Internet
Explorer processes data stream headers in specific situations. An attacker
could exploit the vulnerability by constructing a specially crafted Web page.
When a user views the Web page, the vulnerability could allow remote code
execution. An attacker who successfully exploited this vulnerability could
gain the same user rights as the logged-on user. 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.
HTML Component Handling Vulnerability - CVE-2009-2529
A remote code execution vulnerability exists in the way that Internet
Explorer handles argument validation of a variable in specific situations. An
attacker could exploit the vulnerability by constructing a specially crafted
Web page. When a user views the Web page, the vulnerability could allow
remote code execution. An attacker who successfully exploited this
vulnerability could gain the same user rights as the logged-on user. 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.
Uninitialized Memory Corruption Vulnerability - CVE-2009-2530
A remote code execution vulnerability exists in the way Internet Explorer
accesses an object that has not been correctly initialized or has been
deleted. An attacker could exploit the vulnerability by constructing a
specially crafted Web page. When a user views the Web page, the
vulnerability could allow remote code execution. An attacker who successfully
exploited this vulnerability could gain the same user rights as the
logged-on user. 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.
Uninitialized Memory Corruption Vulnerability - CVE-2009-2531
A remote code execution vulnerability exists in the way Internet Explorer
accesses an object that has not been correctly initialized or has been
deleted. An attacker could exploit the vulnerability by constructing a
specially crafted Web page. When a user views the Web page, the vulnerability
could allow remote code execution. An attacker who successfully exploited
this vulnerability could gain the same user rights as the logged-on user. 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.
