Microsoft released Security Advisory 2963983 regarding an issue that affects Microsoft Internet Explorer versions 6 through 11.
These versions of Internet Explorer have a flaw in how the browser 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 when a user accesses content in Internet Explorer. An attacker could host a specially crafted website that is designed to exploit this flaw through Internet Explorer and then convince a user to view the website.
How will this affect you?
There is currently no patch available for this vulnerability and Microsoft has not, at the time of writing, provided a release date for one. If you are using Internet Explorer as your browser, your computer is at risk of being compromised by malware.
