Security Updates for Internet Explorer (April 2018)

High Nessus Plugin ID 108971

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 VBScript engine handles 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-2018-1004)

- 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-2018-0870, CVE-2018-0991, CVE-2018-0997, CVE-2018-1018, CVE-2018-1020)

- 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-2018-0988, CVE-2018-0996, CVE-2018-1001)

- An information disclosure 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 provide an attacker with information to further compromise the user's computer or data. (CVE-2018-0981, CVE-2018-0989, CVE-2018-1000)

- 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-2018-0987)
