 - A spoofing vulnerability exists when Transport Layer Security (TLS) accesses non- Extended Master Secret (EMS) sessions. An attacker who successfully exploited this vulnerability may gain access to unauthorized information. (CVE-2019-1318)

 - An elevation of privilege vulnerability exists when Windows improperly handles authentication requests. An attacker who successfully exploited this vulnerability could run processes in an elevated context. An attacker could exploit this vulnerability by running a specially crafted application on the victim system. The update addresses the vulnerability by correcting the way Windows handles authentication requests. (CVE-2019-1320, CVE-2019-1322)

 - A remote code execution vulnerability exists in the way that the VBScript engine handles objects in memory. 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. (CVE-2019-1238, CVE-2019-1239)

 - A remote code execution vulnerability exists in the Windows Remote Desktop Client when a user connects to a malicious server. An attacker who successfully exploited this vulnerability could execute arbitrary code on the computer of the connecting client. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
 (CVE-2019-1333)

 - A security feature bypass exists when Windows Secure Boot improperly restricts access to debugging functionality. An attacker who successfully exploited this vulnerability could disclose protected kernel memory. (CVE-2019-1368)

 - A tampering vulnerability exists in Microsoft Windows when a man-in-the-middle attacker is able to successfully bypass the NTLM MIC (Message Integrity Check) protection. An attacker who successfully exploited this vulnerability could gain the ability to downgrade NTLM security features. (CVE-2019-1166)

 - An elevation of privilege vulnerability exists in the Windows redirected drive buffering system (rdbss.sys) when the operating system improperly handles specific local calls within Windows 7 for 32-bit systems. When this vulnerability is exploited within other versions of Windows it can cause a denial of service, but not an elevation of privilege. (CVE-2019-1325)

 - An elevation of privilege vulnerability exists when Windows Error Reporting manager improperly handles hard links. An attacker who successfully exploited this vulnerability could overwrite a targeted file leading to an elevated status. (CVE-2019-1315, CVE-2019-1339)

 - An elevation of privilege vulnerability exists when Microsoft IIS Server fails to check the length of a buffer prior to copying memory to it. An attacker who successfully exploited this vulnerability can allow an unprivileged function ran by the user to execute code in the context of NT AUTHORITY\system escaping the Sandbox.
 The security update addresses the vulnerability by correcting how Microsoft IIS Server sanitizes web requests. (CVE-2019-1365)

 - A spoofing vulnerability exists when Microsoft Browsers improperly handle browser cookies. An attacker who successfully exploited this vulnerability could trick a browser into overwriting a secure cookie with an insecure cookie. The insecure cookie could serve as a pivot to chain an attack with other vulnerabilities in web services. (CVE-2019-1357)

 - An elevation of privilege vulnerability exists when Windows CloudStore improperly handles file Discretionary Access Control List (DACL). An attacker who successfully exploited this vulnerability could overwrite a targeted file leading to an elevated status. (CVE-2019-1321)

 - A remote code execution vulnerability exists when the Windows Jet Database Engine improperly handles objects in memory. An attacker who successfully exploited this vulnerability could execute arbitrary code on a victim system. An attacker could exploit this vulnerability by enticing a victim to open a specially crafted file. The update addresses the vulnerability by correcting the way the Windows Jet Database Engine handles objects in memory. (CVE-2019-1358, CVE-2019-1359)

 - An information disclosure vulnerability exists in the way that the Windows Code Integrity Module handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. (CVE-2019-1344)

 - A remote code execution vulnerability exists when the Windows Imaging API improperly handles objects in memory. The vulnerability could corrupt memory in a way that enables an attacker to execute arbitrary code in the context of the current user. (CVE-2019-1311)

 - A denial of service 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 cause the RDP service on the target system to stop responding. (CVE-2019-1326)

 - An information disclosure vulnerability exists when Windows Update Client fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could potentially disclose memory contents of an elevated process. (CVE-2019-1337)

 - An elevation of privilege vulnerability exists when umpo.dll of the Power Service, improperly handles a Registry Restore Key function. An attacker who successfully exploited this vulnerability could delete a targeted registry key leading to an elevated status.
 (CVE-2019-1341)

 - An elevation of privilege vulnerability exists in Windows Error Reporting (WER) when WER handles and executes files. The vulnerability could allow elevation of privilege if an attacker can successfully exploit it.
 An attacker who successfully exploited the vulnerability could gain greater access to sensitive information and system functionality. (CVE-2019-1319)
