The issue is related to a use-after-free vulnerability in the CDwnBindInfo function of the mshtml.dll library in Internet Explorer. This vulnerability allows a remote attacker to execute arbitrary JavaScript code by sending a specially crafted HTML file. The vulnerability may corrupt memory, enabling an attacker to execute arbitrary code in the context of the current user. It has been exploited in the wild, with reported incidents of remote code execution, including a watering hole attack on the Council on Foreign Relations website in 2012.
