The remote Windows host is missing security update 4074596.
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.
(CVE-2017-5715, CVE-2017-5753, CVE-2017-5754)
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-2018-0866)
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 users system. (CVE-2018-0757, CVE-2018-0829, CVE-2018-0830)
An elevation of privilege vulnerability exists in the way that the Windows Kernel handles objects in memory.
An attacker who successfully exploited the vulnerability could execute code with elevated permissions.
(CVE-2018-0742, CVE-2018-0756, CVE-2018-0820)
An information disclosure vulnerability exists when VBScript improperly discloses the contents of its memory, which could provide an attacker with information to further compromise the users computer or data.
(CVE-2018-0847)
A remote code execution vulnerability exists in StructuredQuery when the software fails to properly handle 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.
(CVE-2018-0825)
An elevation of privilege vulnerability exists when NTFS improperly handles objects. An attacker who successfully exploited this vulnerability could run processes in an elevated context. (CVE-2018-0822)
A remote code execution vulnerability exists in the way that the scripting engine handles objects in memory in Microsoft Edge. 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-2018-0834, CVE-2018-0835, CVE-2018-0837, CVE-2018-0838, CVE-2018-0857, CVE-2018-0859, CVE-2018-0860)
An elevation of privilege vulnerability exists when AppContainer improperly implements constrained impersonation. An attacker who successfully exploited this vulnerability could run processes in an elevated context. (CVE-2018-0821)
A remote code execution vulnerability exists when Windows improperly handles objects in memory. An attacker who successfully exploited these vulnerabilities could take control of an affected system. (CVE-2018-0842)
A remote code execution vulnerability exists in the way the scripting engine handles objects in memory in Microsoft browsers. 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-2018-0840)
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-2018-0832)
An elevation of privilege vulnerability exists when the Windows Common Log File System (CLFS) driver improperly handles objects in memory. An attacker who successfully exploited this vulnerability could run processes in an elevated context. (CVE-2018-0844, CVE-2018-0846)
