A remote code execution vulnerability exists when Internet Explorer improperly accesses objects in memory, aka "Internet Explorer Memory Corruption Vulnerability." This affects Internet Explorer 11. This CVE ID is unique from CVE-2018-8447.

The remote Windows host is missing security update 4457142.
It is, therefore, affected by multiple vulnerabilities :

  - 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-2018-8457)

  - An information disclosure vulnerability exists when the     Windows GDI component improperly discloses the contents     of its memory. An attacker who successfully exploited     the vulnerability could obtain information to further     compromise the users system. There are multiple ways an     attacker could exploit the vulnerability, such as by     convincing a user to open a specially crafted document,     or by convincing a user to visit an untrusted webpage.
    The security update addresses the vulnerability by     correcting how the Windows GDI component handles objects     in memory. (CVE-2018-8424)

  - An elevation of privilege vulnerability exists in     Windows that allows a 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, the vulnerability     could allow arbitrary code to run if an attacker uses it     in combination with another vulnerability, such as a     remote code execution vulnerability or another elevation     of privilege vulnerability, that can leverage the     elevated privileges when code execution is attempted.
    The security update addresses the vulnerability by     correcting how Windows parses files. (CVE-2018-8468)
