The Internet Explorer installation on the remote host is missing security updates. 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 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 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)
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 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.
