Vulnerabilities

An elevation of privilege vulnerability exists in the way that the Windows Graphics Device Interface (GDI) handles objects in memory. 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.<br /> To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system.<br /> The update addresses the vulnerability by correcting how GDI handles objects in memory and by preventing instances of unintended user-mode privilege elevation.

A remote code execution vulnerability exists in Microsoft Outlook when the software fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker could take control of the 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.<br /> Exploitation of the vulnerability requires that a user open a specially crafted file with an affected version of Microsoft Outlook software. In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) that contains a specially crafted file designed to exploit the vulnerability. An attacker would have no way to force users to visit the website. Instead, an attacker would have to convince users to click a link, typically by way of an enticement in an email or instant message, and then convince them to open the specially crafted file.<br /> Note that where severity is indicated as Critical in the Affected Products table, the Preview Pane is an attack vector.<br /> The security update addresses the vulnerability by correcting how Outlook handles objects in memory.

An elevation of privilege vulnerability exists when the Windows Work Folders Service improperly handles memory.<br /> To exploit this vulnerability, an attacker would first have to gain execution on the victim system. An attacker could then run a specially crafted application to elevate privileges.<br /> The security update addresses the vulnerability by correcting how the Windows Work Folders Service handles memory.

An information disclosure vulnerability exists when the Windows Image Acquisition (WIA) Service improperly discloses contents of its memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the user’s system.<br /> To exploit the vulnerability, an authenticated attacker could connect an imaging device (camera, scanner, cellular phone) to an affected system and run a specially crafted application to disclose information.<br /> The security update addresses the vulnerability by correcting how the WIA Service handles objects in memory.

An elevation of privilege vulnerability exists when the Windows kernel fails to properly handle objects in memory. 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.<br /> To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application to take control of an affected system.<br /> The update addresses the vulnerability by correcting how the Windows kernel handles objects in memory.

An information disclosure vulnerability exists when Media Foundation improperly handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the user’s system.<br /> To exploit this vulnerability, an attacker would have to log onto an affected system and open a specially crafted file. In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) that contains a specially crafted file that is designed to exploit the vulnerability. However, an attacker would have no way to force the user to visit the website. Instead, an attacker would have to convince the user to click a link, typically by way of an enticement in an email or Instant Messenger message, and then convince the user to open the specially crafted file.<br /> The update addresses the vulnerability by correcting how Media Foundation handles objects in memory.

An elevation of privilege vulnerability exists when the Windows Print Spooler service improperly allows arbitrary writing to the file system. An attacker who successfully exploited this vulnerability could run arbitrary code with elevated system privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.<br /> To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted script or application.<br /> The update addresses the vulnerability by correcting how the Windows Print Spooler Component writes to the file system.

A remote code execution vulnerability exists when Windows Media Audio Codec improperly handles objects. An attacker who successfully exploited the vulnerability could take control of an affected system.<br /> There are multiple ways an attacker could exploit the vulnerability, such as by convincing a user to open a specially crafted document, or by convincing a user to visit a malicious webpage.<br /> The security update addresses the vulnerability by correcting how Windows Media Audio Codec handles objects.

An elevation of privilege vulnerability exists when the Windows Kernel API improperly handles registry objects in memory. An attacker who successfully exploited the vulnerability could gain elevated privileges on a targeted system.<br /> A locally authenticated attacker could exploit this vulnerability by running a specially crafted application.<br /> The security update addresses the vulnerability by helping to ensure that the Windows Kernel API properly handles objects in memory.

An attacker who successfully exploited the vulnerability could gain elevated privileges on a targeted system.<br /> A locally authenticated attacker could exploit this vulnerability by running a specially crafted application.<br /> The security update addresses the vulnerability by helping to ensure that the Windows Kernel API properly handles objects in memory.

A memory corruption vulnerability exists when Windows Media Foundation improperly handles objects in memory. An attacker who successfully exploited the vulnerability could install programs; view, change, or delete data; or create new accounts with full user rights.<br /> There are multiple ways an attacker could exploit the vulnerability, such as by convincing a user to open a specially crafted document, or by convincing a user to visit a malicious webpage.<br /> The security update addresses the vulnerability by correcting how Windows Media Foundation handles objects in memory.

A remote code execution vulnerability exists in the way that the scripting engine handles objects in memory in Internet Explorer. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.<br /> In a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit the vulnerability through Internet Explorer and then convince a user to view the website. An attacker could also embed an ActiveX control marked &amp;quot;safe for initialization&amp;quot; in an application or Microsoft Office document that hosts the IE rendering engine. The attacker could also take advantage of compromised websites and websites that accept or host user-provided content or advertisements. These websites could contain specially crafted content that could exploit the vulnerability.<br /> The security update addresses the vulnerability by modifying how the scripting engine handles objects in memory.
