weiter.
CVE-2009-2515 - Integer Underflow Schwachstelle im Microsoft Windows
Kernel
Im Microsoft Windows Kernel kann bei der Kuerzung von 64-Bit auf
32-Bit Werten ein Integer Underflow Fehler auftreten. Ein lokaler
Angreifer kann diese Schwachstelle zum Ausfuehren von beliebigen
Befehlen mit SYSTEM Rechten ausnutzen, in dem er ein einsprechend
aufgebautes Programm ausfuehrt.
CVE-2009-2516 - NULL Pointer Dereferenzierung im Windows Kernel
In dem Microsoft Windows Kernel werden bestimmte Daten vom User Mode
an den Kernel nicht ausreichend ueberprueft und dadurch kann eine NULL
Pointer Dereferenzierung ausgeloest werden. Ein lokaler Angreifer kann
diese Schwachstelle zum Ausfuehren beliebiger Befehle mit SYSTEM
Rechten, wenn er ein entsprechend aufgebautes Programm startet.
CVE-2009-2517 - Schwachstelle im Windows Kernel bei der
Ausnahmebehandlung
In dem Microsoft Windows Kernel werden bestimmte Fehlerbehandlungen
nicht korrekt durchgefuehrt. Diese Schwachstelle kann ein lokaler
Angreifer zum Neustart des Systems ausnutzen (Denial of Service), in
dem er ein entsprechend aufgebautes Programm auf dem System ausfuehrt.

Microsoft Security Bulletin MS09-058 - Important
Vulnerabilities in Windows Kernel Could Allow Elevation of Privilege (971486)
Published: October 13, 2009
Version: 1.0
General Information
Executive Summary
This security update resolves several privately reported vulnerabilities in
the Windows kernel. The most severe of the vulnerabilities could allow
elevation of privilege if an attacker logged on to the system and ran a
specially crafted application. An attacker must have valid logon credentials
and be able to log on locally to exploit any of these vulnerabilities. The
vulnerabilities could not be exploited remotely or by anonymous users.
This security update is rated Important for supported editions of Microsoft
Windows 2000, Windows XP, Windows Server 2003, Windows Vista, and Windows
Server 2008; and Moderate for Service Pack 2 for all editions of Windows
Vista and Windows Server 2008. For more information, see the subsection,
Affected and Non-Affected Software, in this section.
The security update addresses the vulnerabilities by ensuring that the
Windows kernel truncates 64-bit values properly, ensuring that the Windows
kernel properly validates data within an executable, and ensuring that the
Windows kernel cleans up exceptions under error conditions.
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 at the earliest opportunity using update management
software, or by checking for updates using the Microsoft Update service.
Known Issues. None

Vulnerability Information
Windows Kernel Integer Underflow Vulnerability - CVE-2009-2515
An elevation of privilege vulnerability exists in the Windows kernel due to
the incorrect truncation of a 64-bit value to a 32-bit value. An attacker
who successfully exploited this vulnerability could run arbitrary code in
kernel mode. An attacker could then install programs; view, change, or
delete data; or create new accounts with full user rights.
Windows Kernel NULL Pointer Dereference Vulnerability - CVE-2009-2516
An elevation of privilege vulnerability exists in the Windows kernel due to
the insufficient validation of certain data passed from user mode. An
attacker who successfully exploited this vulnerability could run arbitrary
code in kernel mode. An attacker could then install programs; view, change,
or delete data; or create new accounts with full user rights.
Windows Kernel Exception Handler Vulnerability - CVE-2009-2517
A denial of service vulnerability exists in the Windows kernel because of
the way the kernel handles certain exceptions. An attacker could exploit
the vulnerability by running a specially crafted application causing the
system to restart.
