Synopsis
The remote Windows host is affected by multiple vulnerabilities.Description
The remote Windows host is missing security update 4457145 or cumulative update 4457144. 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 when the Windows Kernel API improperly handles registry objects in memory. An attacker who successfully exploited the vulnerability could gain elevated privileges on a targeted system. A locally authenticated attacker could exploit this vulnerability by running a specially crafted application. The security update addresses the vulnerability by helping to ensure that the Windows Kernel API properly handles objects in memory.
(CVE-2018-8410)
- An elevation of privilege vulnerability exists when Windows improperly handles calls to Advanced Local Procedure Call (ALPC). An attacker who successfully exploited this vulnerability could run arbitrary code in the security context of the local system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
(CVE-2018-8440)
- A buffer overflow vulnerability exists in the Microsoft JET Database Engine that could allow remote code execution on an affected system. 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. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. (CVE-2018-8392, CVE-2018-8393)
- A remote code execution vulnerability exists when Windows does not properly handle specially crafted image files. An attacker who successfully exploited the vulnerability could execute arbitrary code.
(CVE-2018-8475)
- A remote code execution vulnerability exists when Microsoft .NET Framework processes input. An attacker who successfully exploited this vulnerability could take control of an affected system. (CVE-2018-8421)
- An information disclosure vulnerability exists when the Windows Graphics component improperly handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. An authenticated attacker could exploit this vulnerability by running a specially crafted application. The update addresses the vulnerability by correcting how the Windows Graphics Component handles objects in memory. (CVE-2018-8433)
- 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-2018-8447)
- A remote code execution vulnerability exists when the Microsoft XML Core Services MSXML parser processes user input. An attacker who successfully exploited the vulnerability could run malicious code remotely to take control of the users system. (CVE-2018-8420)
- 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-2018-8452)
- 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)
- An information disclosure vulnerability exists when the Windows kernel improperly handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. An authenticated attacker could exploit this vulnerability by running a specially crafted application. The update addresses the vulnerability by correcting how the Windows kernel handles objects in memory. (CVE-2018-8442, CVE-2018-8443)
- An information disclosure vulnerability exists when the Windows kernel fails to properly initialize a memory address. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. (CVE-2018-8419)
- An information disclosure vulnerability exists when Windows Hyper-V on a host operating system fails to properly validate input from an authenticated user on a guest operating system. (CVE-2018-8434)
- An information disclosure vulnerability exists in Windows when the Windows bowser.sys kernel-mode driver fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could potentially disclose contents of System memory.
(CVE-2018-8271)
- A remote code execution vulnerability exists when the Windows font library improperly handles specially crafted embedded fonts. An attacker who successfully exploited this vulnerability could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2018-8332)
- An information disclosure vulnerability exists when the browser scripting engine improperly handle object types.
An attacker who has successfully exploited this vulnerability might be able to read privileged data across trust boundaries. In browsing scenarios, an attacker could convince a user to visit a malicious site and leverage the vulnerability to obtain privileged information from the browser process, such as sensitive data from other opened tabs. An attacker could also inject malicious code into advertising networks used by trusted sites or embed malicious code on a compromised, but trusted, site. The security update addresses the vulnerability by correcting how the browser scripting engine handles object types. (CVE-2018-8315)
- A security feature bypass vulnerability exists in Internet Explorer due to how scripts are handled that allows a universal cross-site scripting (UXSS) condition. An attacker could use the UXSS vulnerability to access any session belonging to web pages currently opened (or cached) by the browser at the time the attack is triggered. (CVE-2018-8470)
- An information disclosure vulnerability exists when the Windows kernel improperly handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. (CVE-2018-8336, CVE-2018-8446)
