The remote Windows host is missing security update 4088878 or cumulative update 4088875. It is, therefore, affected by multiple vulnerabilities :

  - An vulnerability exists within microprocessors utilizing     speculative execution and indirect branch prediction,     which may allow an attacker with local user access to     disclose information via a side-channel analysis.
    Note: this patch applies to only 32-bit Windows 7     systems.
    (CVE-2017-5715, CVE-2017-5753, CVE-2017-5754)

  - An information disclosure vulnerability exists when     Windows Remote Assistance incorrectly processes XML     External Entities (XXE). An attacker who successfully     exploited the vulnerability could obtain information to     further compromise the users system.  (CVE-2018-0878)

  - An information disclosure vulnerability exists when     Internet Explorer improperly handles objects in memory.
    An attacker who successfully exploited the vulnerability     could obtain information to further compromise the users     system.  (CVE-2018-0929)

  - A remote code execution vulnerability exists when     Windows Shell does not properly validate file copy     destinations. 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.  (CVE-2018-0883)

  - An elevation of privilege vulnerability exists in     Windows when the Microsoft Video Control mishandles     objects in memory. An attacker who successfully     exploited this vulnerability could run arbitrary code in     system mode. An attacker could then install programs;
    view, change, or delete data; or create new accounts     with full user rights.  (CVE-2018-0881)

  - An information disclosure vulnerability exists when     affected Microsoft browsers improperly handle objects in     memory. An attacker who successfully exploited this     vulnerability could obtain information to further     compromise the users system.  (CVE-2018-0927,     CVE-2018-0932)

  - 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.
    (CVE-2018-0889, CVE-2018-0935)

  - An elevation of privilege vulnerability exists when     Internet Explorer fails a check, allowing sandbox     escape. An attacker who successfully exploited the     vulnerability could use the sandbox escape to elevate     privileges on an affected system. This vulnerability by     itself does not allow arbitrary code execution; however,     it could allow arbitrary code to be run if the attacker     uses it in combination with another vulnerability (such     as a remote code execution vulnerability or another     elevation of privilege vulnerability) that is capable of     leveraging the elevated privileges when code execution     is attempted. The update addresses the vulnerability by     correcting how Internet Explorer handles zone and     integrity settings. (CVE-2018-0942)

  - An information disclosure vulnerability exists when the     Windows kernel improperly initializes objects in memory.
    (CVE-2018-0811, CVE-2018-0813, CVE-2018-0814)

  - A denial of service vulnerability exists when Microsoft     Hyper-V Network Switch on a host server fails to     properly validate input from a privileged user on a     guest operating system. An attacker who successfully     exploited the vulnerability could cause the host server     to crash.  (CVE-2018-0885)

  - An information disclosure vulnerability exists in the     Windows kernel that could allow an attacker to retrieve     information that could lead to a Kernel Address Space     Layout Randomization (ASLR) bypass. An attacker who     successfully exploited the vulnerability could retrieve     the memory address of a kernel object.  (CVE-2018-0894,     CVE-2018-0895, CVE-2018-0896, CVE-2018-0897,     CVE-2018-0898, CVE-2018-0899, CVE-2018-0900,     CVE-2018-0901, CVE-2018-0904)

  - 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. 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. The security update addresses the vulnerability     by correcting the input sanitization error to preclude     unintended elevation. (CVE-2018-0868)

  - A remote code execution vulnerability exists in the     Credential Security Support Provider protocol (CredSSP).
    An attacker who successfully exploited this     vulnerability could relay user credentials and use them     to execute code on the target system. CredSSP is an     authentication provider which processes authentication     requests for other applications; any application which     depends on CredSSP for authentication may be vulnerable     to this type of attack. As an example of how an attacker     would exploit this vulnerability against Remote Desktop     Protocol, the attacker would need to run a specially     crafted application and perform a man-in-the-middle     attack against a Remote Desktop Protocol session. An     attacker could then install programs; view, change, or     delete data; or create new accounts with full user     rights. The security update addresses the vulnerability     by correcting how Credential Security Support Provider     protocol (CredSSP) validates requests during the     authentication process. To be fully protected against     this vulnerability users must enable Group Policy     settings on their systems and update their Remote     Desktop clients. The Group Policy settings are disabled     by default to prevent connectivity problems and users     must follow the instructions documented HERE to be fully     protected. (CVE-2018-0886)

  - 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.  (CVE-2018-0815, CVE-2018-0816,     CVE-2018-0817)

  - An information disclosure vulnerability exists when     Windows Hyper-V on a host operating system fails to     properly validate input from an authenticated user on a     guest operating system.  (CVE-2018-0888)

  - An information disclosure vulnerability exists when the     scripting engine does not properly handle objects in     memory in Microsoft browsers. An attacker who     successfully exploited the vulnerability could obtain     information to further compromise the users system.
    (CVE-2018-0891)
