Security Updates for Windows Server 2008 (July 2018)

High Nessus Plugin ID 111007

Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

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

- A denial of service vulnerability exists in Windows Domain Name System (DNS) DNSAPI.dll when it fails to properly handle DNS responses. An attacker who successfully exploited the vulnerability could cause a system to stop responding. Note that the denial of service condition would not allow an attacker to execute code or to elevate user privileges. However, the denial of service condition could prevent authorized users from using system resources. (CVE-2018-8304)

- A denial of service vulnerability exists when Windows improperly handles objects in memory. An attacker who successfully exploited the vulnerability could cause a target system to stop responding. (CVE-2018-8309)

- An elevation of privilege vulnerability exists in Windows when the Windows kernel-mode driver 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-2018-8282)

- A denial of service vulnerability exists when Windows improperly handles File Transfer Protocol (FTP) connections. An attacker who successfully exploited the vulnerability could cause a target system to stop responding. (CVE-2018-8206)

- An elevation of privilege vulnerability exists when Windows fails a check, allowing 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 file picker handles paths. (CVE-2018-8314)

- 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-2018-8308)

- A security feature bypass vulnerability exists when Microsoft WordPad improperly handles embedded OLE objects. An attacker who successfully exploited the vulnerability could bypass content blocking. In a file- sharing attack scenario, an attacker could provide a specially crafted document file designed to exploit the vulnerability, and then convince a user to open the document file. The security update addresses the vulnerability by correcting how Microsoft WordPad handles input. (CVE-2018-8307)

Solution

Microsoft has released security updates for Windows Server 2008.
