NASL family Windows : Microsoft Bulletins NASL id SMB_NT_MS18_DEC_4471323.NASL description The remote Windows host is missing security update 4471323. It is, therefore, affected by multiple vulnerabilities : - 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-2018-8631) - 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-2018-8595, CVE-2018-8596) - A remote code execution vulnerability exists in Windows where Microsoft text-to-speech fails to properly handle objects in the memory. 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-2018-8634) - A remote code execution vulnerability exists when the Microsoft .NET Framework fails to validate input properly. 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-2018-8540) - An elevation of privilege vulnerability exists in Windows when the Win32k component fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2018-8639) - An elevation of privilege vulnerability exists when the Diagnostics Hub Standard Collector Service improperly impersonates certain file operations. An attacker who successfully exploited this vulnerability could gain elevated privileges. An attacker with unprivileged access to a vulnerable system could exploit this vulnerability. The security update addresses the vulnerability by ensuring the Diagnostics Hub Standard Collector Service properly impersonates file operations. (CVE-2018-8599) - A remote code execution vulnerability exists in the way that the Chakra scripting engine handles objects in memory in Microsoft Edge. 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-2018-8617, CVE-2018-8629) - 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-2018-8477) - An information disclosure vulnerability exists when Remote Procedure Call runtime improperly initializes objects in memory. (CVE-2018-8514) - An elevation of privilege vulnerability exists when the Windows kernel fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2018-8611) - 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-2018-8625) - A remote code execution vulnerability exists when the Internet Explorer VBScript execution policy does not properly restrict VBScript under specific conditions. An attacker who exploited the vulnerability could run arbitrary code with medium-integrity level privileges (the permissions of the current user). (CVE-2018-8619) - 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-2018-8643) - An elevation of privilege vulnerability exists in Windows when the Windows kernel-mode driver fails to properly handle objects in memory.
