Security Updates for Internet Explorer (March 2018)

high Nessus Plugin ID 108295

Synopsis

The Internet Explorer installation on the remote host is affected by multiple vulnerabilities.

Description

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 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 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)

- 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)

- 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)

Solution

Microsoft has released the following security updates to address this issue:
-KB4088876
-KB4088877
-KB4088875
-KB4089187
