An information disclosure vulnerability exists when the win32k component improperly provides kernel information. An attacker who successfully exploited the vulnerability could obtain information to further compromise the user’s system. To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The security update addresses the vulnerability by correcting how win32k handles objects in memory.

An elevation of privilege vulnerability exists in the Local Security Authority Subsystem Service (LSASS) when an authenticated attacker sends a specially crafted authentication request. A remote attacker who successfully exploited this vulnerability could cause an elevation of privilege on the target system's LSASS service. The security update addresses the vulnerability by changing the way that LSASS handles specially crafted authentication requests.

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. 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. The security update addresses the vulnerability by correcting how Windows Media Foundation handles objects in memory.

An elevation of privilege vulnerability exists when the Storage Service improperly handles file operations. An attacker who successfully exploited this vulnerability could gain elevated privileges on the victim system. To exploit the vulnerability, an attacker would first have to gain execution on the victim system, then run a specially crafted application. The security update addresses the vulnerability by correcting how the Storage Services handles file operations.

An elevation of privilege vulnerability exists when the Windows CSC Service improperly handles memory. 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. The security update addresses the vulnerability by correcting how the Windows CSC Service handles memory.

An elevation of privilege vulnerability exists when the Windows AppX Deployment Extensions improperly performs privilege management, resulting in access to system files. To exploit this vulnerability, an authenticated attacker would need to run a specially crafted application to elevate privileges. The security update addresses the vulnerability by correcting how AppX Deployment Extensions manages privileges.

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. 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. The update addresses the vulnerability by correcting how Media Foundation 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. 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. The update addresses the vulnerability by correcting how the Windows kernel handles objects in 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. 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. 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 Work Folders Service improperly handles memory. 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. The security update addresses the vulnerability by correcting how the Windows Work Folders Service handles memory.

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. 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. The update addresses the vulnerability by correcting how GDI handles objects in memory and by preventing instances of unintended user-mode privilege elevation.
