Vulnerability Note VU#239151

Microsoft Internet Explorer 8 CMarkup use-after-free vulnerability

Original Release date: 21 May 2014 | Last revised: 23 May 2014

Overview

Microsoft Internet Explorer 8 contains a use-after-free vulnerability that can allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.

Description

Microsoft Internet Explorer 8 contains a use-after-free vulnerability. This can allow for arbitrary code execution. Additional details may be found in the Zero Day Initiative advisory ZDI-14-140.

Impact

By convincing a user to view a specially crafted HTML document (e.g., a web page or an HTML email message or attachment), an attacker may be able to execute arbitrary code.

Solution

Apply an Update

Users should upgrade to Internet Explorer 11.

Users that are unable to upgrade past Internet Explorer 8 should consider the following workarounds. Windows XP users will not be able to upgrade past Internet Explorer 8.

Use the Microsoft Enhanced Mitigation Experience Toolkit

The Microsoft Enhanced Mitigation Experience Toolkit (EMET) can be used to help prevent exploitation of this vulnerability. Note that platforms that do not support ASLR, such as Windows XP and Windows Server 2003, will not receive the same level of protection that modern Windows platforms will.

Disable ActiveX and Active Scripting

Set the Internet security zone setting to "High" to block ActiveX Controls and Active Scripting.
