Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

The remote Windows host is missing security update 4507460.
It is, therefore, affected by multiple vulnerabilities :

- An elevation of privilege vulnerability exists when DirectX improperly handles 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-2019-0999)

- A remote code execution vulnerability exists in .NET software when the software fails to check the source markup of a file. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker 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-2019-1113)

- A local elevation of privilege vulnerability exists in how splwow64.exe handles certain calls. An attacker who successfully exploited the vulnerability could elevate privileges on an affected system from low-integrity to medium-integrity. This vulnerability by itself does not allow arbitrary code execution; however, it could allow arbitrary code to be run if the attacker uses it in combination with another vulnerability (such as a remote code execution vulnerability or another elevation of privilege vulnerability) that is capable of leveraging the elevated privileges when code execution is attempted. (CVE-2019-0880)

- An elevation of privilege vulnerability exists in rpcss.dll when the RPC service Activation Kernel improperly handles an RPC request. (CVE-2019-1089)

- A remote code execution vulnerability exists in the way that the Chakra scripting engine handles objects in memory in Microsoft Edge.

- 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-2019-1104)

- An information disclosure vulnerability exists when DirectWrite 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 DirectWrite handles objects in memory.
(CVE-2019-1093, CVE-2019-1097)

- 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-2019-1094, CVE-2019-1095)

- 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-2019-1071)

- 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-2019-1067)

- An elevation of privilege exists in Windows Audio Service. An attacker who successfully exploited the vulnerability could run arbitrary code with elevated privileges. (CVE-2019-1086, CVE-2019-1087, CVE-2019-1088)

- An elevation of privilege vulnerability exists when Windows AppX Deployment Service (AppXSVC) improperly handles hard links. An attacker who successfully exploited this vulnerability could run processes in an elevated context. An attacker could then install programs; view, change or delete data. (CVE-2019-1130)

- 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-2019-1004, CVE-2019-1056, CVE-2019-1059)
