Descriptions

Microsoft Internet Explorer 10 and 11 and Microsoft Edge allow remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site, aka "Microsoft Browser Memory Corruption Vulnerability."

Microsoft Internet Explorer 10 y 11 y Microsoft Edge permiten a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (corrupción de memoria) a través de un sitio web manipulado, vulnerabilidad también conocida como "Microsoft Browser Memory Corruption Vulnerability".

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Edge. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw relates to how Edge handles text nodes within HTML documents. By manipulating a document's elements an attacker can cause Microsoft Edge to use a pointer to a CTreePos as if it were a pointer to a Tree::ANode. An attacker can leverage this vulnerability to execute code under the context of the current process.
