Windows IOleCvt Interface Remote Code Execution Vulnerability - CVE-2019-0845


A remote code execution vulnerability exists when the IOleCvt interface renders ASP webpage content. An attacker who successfully exploited the vulnerability could run malicious code remotely to take control of the user’s system. In a web-based attack scenario an attacker could host a specially crafted website designed to exploit the vulnerability through Microsoft browsers and then convince a user to view the website. An attacker could also embed an ActiveX control marked "safe for initialization" in an application or Microsoft Office document that hosts the browser rendering engine. The attacker could also take advantage of compromised websites and websites that accept or host user-provided content or advertisements. These websites could contain specially crafted content that could exploit the vulnerability. The update addresses the vulnerability by correcting methods exposed when the IOleCvt interface is invoked.
