Vulnerability in Internet Explorer Could Allow Remote Code Execution
By convincing a user to view a specially crafted HTML document, an attacker may be able to execute malicious code. Microsoft is aware of limited, targeted attacks that attempt to exploit this vulnerability in Internet Explorer 6, Internet Explorer 7, Internet Explorer 8, Internet Explorer 9, Internet Explorer 10, and Internet Explorer 11.
The “zero-day” threat affects Internet Explorer browsers across multiple Microsoft operating systems. But the situation poses a special concern for people still using Windows XP because security updates and patches ceased after April 8th, 2014.
You can visit Microsoft’s website regarding the Security Advisory 2963983 for more information, updates, and suggested actions.
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 its 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. 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 anti-malware software.
