Vulnerability in Internet Explorer Could Allow Remote Code Execution »

Microsoft is aware of limited, targeted attacks that attempt to exploit a vulnerability in Internet Explorer 6, Internet Explorer 7, Internet Explorer 8, Internet Explorer 9, Internet Explorer 10, and Internet Explorer 11.

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 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.

This patch will not, however, protect continued users of Windows XP, as Microsoft has discontinued support for that operating system. For those using Windows XP it is recommended that they either upgrade their operating systems or purchase a newer machine. It is also strongly recommended that continuing users of Windows XP do not use Windows Internet Explorer, but instead use other web browsers, such as Google Chrome or Mozilla Firefox.
