<p>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.</p>
<p>To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted script or application.</p>
<p>The update addresses the vulnerability by correcting how the Windows Print Spooler Component writes to the file system.</p>
<p>An information disclosure vulnerability exists in the way that the Windows Server DHCP service improperly discloses the contents of its memory.</p>
<p>To exploit the vulnerability, an unauthenticated attacker could send a specially crafted packet to an affected DHCP server. An attacker who successfully exploited this vulnerability could obtain information to further compromise the user’s system.</p>
<p>The security update addresses the vulnerability by correcting how DHCP servers initializes memory.</p>
<p>An information disclosure vulnerability exists when the Windows kernel improperly handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the user’s system.</p>
<p>To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The vulnerability would not allow an attacker to execute code or to elevate user rights directly, but it could be used to obtain information that could be used to try to further compromise the affected system.</p>
<p>The update addresses the vulnerability by correcting how the Windows kernel handles objects in memory.</p>
<p>A security feature bypass vulnerability exists in Windows Defender Application Control (WDAC) which could allow an attacker to bypass WDAC enforcement. An attacker who successfully exploited this vulnerability could execute PowerShell commands that would be blocked by WDAC.</p>
<p>To exploit the vulnerability, an attacker need administrator access on a local machine where PowerShell is running. The attacker could then connect to a PowerShell session and send commands to execute arbitrary code.</p>
<p>The update addresses the vulnerability by correcting how PowerShell commands are validated when WDAC protection is enabled.</p>
<p>An information disclosure vulnerability exists when Windows Mobile Device Management (MDM) Diagnostics improperly handles junctions. An attacker who successfully exploited this vulnerability could bypass access restrictions to read files.</p>
<p>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 access files.</p>
<p>The security update addresses the vulnerability by correcting the how Windows MDM Diagnostics handles files.</p>
<p>A remote code execution vulnerability exists when the Windows Camera Codec Pack improperly handles 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.</p>
<p>Exploitation of the vulnerability requires that a user open a specially crafted file with an affected version of the Windows Camera Codec Pack. 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) containing 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.</p>
<p>The security update addresses the vulnerability by correcting how the Windows Camera Codec Pack handles objects in memory.</p>
<p>An elevation of privilege vulnerability exists when the Windows Graphics Component improperly handles objects in memory. An attacker who successfully exploited this vulnerability could run processes in an elevated context.</p>
<p>In a local attack scenario, an attacker could exploit this vulnerability by running a specially crafted application to take control over the affected system.</p>
<p>The update addresses the vulnerability by correcting the way in which the Microsoft Graphics Component handles objects in memory and preventing unintended elevation from user mode.</p>
<p>An elevation of privilege vulnerability exists when NTFS improperly checks access. An attacker who successfully exploited this vulnerability could run processes in an elevated context.</p>
<p>To exploit the vulnerability, an attacker would first have to log on to the system, and then run a specially crafted application to take control over the affected system.</p>
<p>The security update addresses the vulnerability by correcting how NTFS checks access.</p>
<p>An elevation of privilege vulnerability exists in the way that the dnsrslvr.dll handles objects in memory. An attacker who successfully exploited the vulnerability could execute code with elevated permissions.</p>
<p>To exploit the vulnerability, a locally authenticated attacker could run a specially crafted application.</p>
<p>The security update addresses the vulnerability by ensuring the dnsrslvr.dll properly handles objects in memory.</p>
<p>An elevation of privilege vulnerability exists when the Shell infrastructure component improperly handles objects in memory. An attacker who successfully exploited this vulnerability could run processes in an elevated context.</p>
<p>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.</p>
<p>The update addresses the vulnerability by correcting the way in which the Shell infrastructure component handles objects in memory and preventing unintended elevation from lower integrity application.</p>
