Windows 10: CVE-2018-8245 Microsoft Publisher Remote Code Execution Vulnerability

Brink · Jun 15, 2018

A remote code execution vulnerability exists when Microsoft Publisher fails to utilize features that lock down the Local Machine zone when instantiating OLE objects. An attacker who successfully exploited the vulnerability could force arbitrary code to be executed in the Local Machine zone.

To exploit the vulnerability, the attacker could send a specially crafted Publisher document to a victim. The user would then need to open the document in Publisher to trigger the vulnerability.

This update addresses the vulnerability by ensuring that Publisher properly utilizes built-in OS functionality to lock down the Local Machine zone.

CVE-2018-0986 | Microsoft Malware Protection Engine Vulnerability

A remote code execution vulnerability exists when the Microsoft Malware Protection Engine does not properly scan a specially crafted file, leading to memory corruption. An attacker who successfully exploited this vulnerability could execute arbitrary code in the security context of the LocalSystem account and take control of the system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

To exploit this vulnerability, a specially crafted file must be scanned by an affected version of the Microsoft Malware Protection Engine. There are many ways that an attacker could place a specially crafted file in a location that is scanned by the Microsoft Malware Protection Engine. For example, an attacker could use a website to deliver a specially crafted file to the victim's system that is scanned when the website is viewed by the user. An attacker could also deliver a specially crafted file via an email message or in an Instant Messenger message that is scanned when the file is opened. In addition, an attacker could take advantage of websites that accept or host user-provided content, to upload a specially crafted file to a shared location that is scanned by the Malware Protection Engine running on the hosting server.

If the affected antimalware software has real-time protection turned on, the Microsoft Malware Protection Engine will scan files automatically, leading to exploitation of the vulnerability when the specially crafted file is scanned. If real-time scanning is not enabled, the attacker would need to wait until a scheduled scan occurs in order for the vulnerability to be exploited. All systems running an affected version of antimalware software are primarily at risk.

The update addresses the vulnerability by correcting the manner in which the Microsoft Malware Protection Engine scans specially crafted files.

Note: Typically, no action is required of enterprise administrators or end users to install updates for the Microsoft Malware Protection Engine, because the built-in mechanism for the automatic detection and deployment of updates will apply the update within 48 hours of release. The exact time frame depends on the software used, Internet connection, and infrastructure configuration.
