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-2018-8353, CVE-2018-8371, CVE-2018-8373, CVE-2018-8389)
- 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-2018-8403)
- 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-2018-8355, CVE-2018-8372, CVE-2018-8385)
- An information disclosure vulnerability exists when affected Microsoft browsers improperly allow cross-frame interaction. An attacker who successfully exploited this vulnerability could allow an attacker to obtain browser frame or window state from a different domain. For an attack to be successful, an attacker must persuade a user to open a malicious website from a secure website.
This update addresses the vulnerability by denying permission to read the state of the object model, to which frames or windows on different domains should not have access. (CVE-2018-8351)
- A remote code execution vulnerability exists when Internet Explorer improperly validates hyperlinks before loading executable libraries. An attacker who successfully exploited this vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
(CVE-2018-8316)
