<p>A remote code execution vulnerability exists when Windows Hyper-V on a host server fails to properly validate input from an authenticated user on a guest operating system. To exploit the vulnerability, an attacker could run a specially crafted application on a guest operating system that could cause the Hyper-V host operating system to execute arbitrary code.</p>

<p>An information disclosure vulnerability exists in Remote Desktop Protocol (RDP) when an attacker connects to the target system using RDP and sends specially crafted requests. 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 need to run a specially crafted application against a server which provides Remote Desktop Protocol (RDP) services.</p>
<p>The update addresses the vulnerability by correcting how RDP handles connection requests.</p>

<p>An information disclosure vulnerability exists when NetBIOS over TCP (NBT) Extensions (NetBT) improperly handle 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 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 a NetBT handles objects in memory.</p>

<p>An elevation of privilege vulnerability exists when the Windows Event System improperly handles objects in memory.</p>
<p>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.</p>
<p>The security update addresses the vulnerability by correcting how the Windows Event System handles objects in memory.</p>

<p>An elevation of privilege vulnerability exists in the Windows Installer when the Windows Installer fails to properly sanitize input leading to an insecure library loading behavior.</p>
<p>A locally authenticated attacker 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>The security update addresses the vulnerability by correcting the input sanitization error to preclude unintended elevation.</p>

Adobe Flash Player version 32.0.0.433 (and earlier) are affected by an exploitable NULL pointer dereference vulnerability that could result in a crash and arbitrary code execution. Exploitation of this issue requires an attacker to insert malicious strings in an HTTP response that is by default delivered over TLS/SSL.
