Microsoft Security Advisory (2847140)
Vulnerability in Internet Explorer Could Allow Remote Code Execution
Published: | Updated:
Version: 1.1
General Information
Executive Summary
Microsoft is investigating public reports of a vulnerability in Internet Explorer 8. Microsoft is aware of attacks that attempt to exploit this vulnerability. Applying the Microsoft Fix it solution, "CVE-2013-1347 MSHTML Shim Workaround," prevents the exploitation of this issue. See the Suggested Actions section of this advisory for more information.
The vulnerability does not affect Internet Explorer 6, Internet Explorer 7, Internet Explorer 9, and Internet Explorer 10.
The vulnerability is a remote code execution vulnerability. The vulnerability exists in the way that Internet Explorer accesses an object in memory that has been deleted or has not been properly allocated. The vulnerability may corrupt memory in a way that could allow an attacker to execute arbitrary code in the context of the current user within Internet Explorer. An attacker could host a specially crafted website that is designed to exploit this vulnerability through Internet Explorer and then convince a user to view the website.
On completion of this investigation, Microsoft will take the appropriate action to protect our customers, which may include providing a solution through our monthly security update release process, or an out-of-cycle security update, depending on customer needs.
We are actively working with partners in our Microsoft Active Protections Program (MAPP) to provide information that they can use to provide broader protections to customers. In addition, we are actively working with partners to monitor the threat landscape and take action against malicious sites that attempt to exploit this vulnerability.
Microsoft continues to encourage customers to follow the guidance in the Microsoft Safety & Security Center of enabling a firewall, applying all software updates, and installing antimalware software.
