The remote Windows host is missing security update 4048956.
It is, therefore, affected by multiple vulnerabilities :
A remote code execution vulnerability exists in the way that Microsoft browsers access objects in memory. The vulnerability could corrupt memory in a way that could allow an attacker to 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-2017-11827, CVE-2017-11858)
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-2017-11837, CVE-2017-11838, CVE-2017-11843, CVE-2017-11846)
A security feature bypass exists when Device Guard incorrectly validates an untrusted file. An attacker who successfully exploited this vulnerability could make an unsigned file appear to be signed. Because Device Guard relies on the signature to determine the file is non- malicious, Device Guard could then allow a malicious file to execute. In an attack scenario, an attacker could make an untrusted file appear to be a trusted file. The update addresses the vulnerability by correcting how Device Guard handles untrusted files.
(CVE-2017-11830)
A remote code execution vulnerability exists when Internet Explorer improperly accesses 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-2017-11855, CVE-2017-11856, CVE-2017-11869)
An information vulnerability exists when Windows Media Player improperly discloses file information. Successful exploitation of the vulnerability could allow the attacker to test for the presence of files on disk.
(CVE-2017-11768)
An information disclosure vulnerability exists when the scripting engine does not properly handle objects in memory in Internet Explorer. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system.
(CVE-2017-11834)
A security feature bypass vulnerability exists in Microsoft Edge when the Edge Content Security Policy (CSP) fails to properly validate certain specially crafted documents. An attacker who exploited the bypass could trick a user into loading a page containing malicious content. (CVE-2017-11863)
An information disclosure vulnerability exists when the Windows kernel improperly initializes objects in memory.
(CVE-2017-11880)
A Win32k information disclosure vulnerability exists when the Windows GDI component improperly discloses kernel memory addresses. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. (CVE-2017-11851)
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-2017-11791)
An elevation of privilege vulnerability exists when the Windows kernel fails to properly handle 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-2017-11847)
An information disclosure vulnerability exists when Internet Explorer improperly handles page content, which could allow an attacker to detect the navigation of the user leaving a maliciously crafted page.
(CVE-2017-11848)
An information disclosure vulnerability exists when the Windows kernel fails to properly initialize a memory address. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. (CVE-2017-11831, CVE-2017-11842, CVE-2017-11849, CVE-2017-11853)
A denial of service vulnerability exists when Windows Search improperly handles objects in memory. An attacker who successfully exploited the vulnerability could cause a remote denial of service against a system.
(CVE-2017-11788)
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-2017-11836, CVE-2017-11839, CVE-2017-11840, CVE-2017-11841, CVE-2017-11866)
An information disclosure vulnerability exists when the Microsoft Windows Graphics Component improperly handles objects in memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. (CVE-2017-11850)
An information disclosure vulnerability exists in the way that Microsoft Edge handles cross-origin requests.
An attacker who successfully exploited this vulnerability could determine the origin of all webpages in the affected browser. (CVE-2017-11833)
