Microsoft Security Advisory for Remote Code Execution Vulnerability in IE

[Corrine]

Microsoft released Security Advisory ADV200001 for a remote code execution vulnerability with limited active attacks in Internet Explorer. The issue is described as the way that the scripting engine handles objects in memory in Internet Explorer. As described in the advisory:

The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

In the event you use Internet Explorer, it is strongly advised that you follow the instructions at the bottom of the Advisory to restrict access to JScript.dll as a workaround.
