Descriptions

Microsoft Edge allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site, aka "Microsoft Edge Memory Corruption Vulnerability."

Microsoft Edge permite a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (corrupción de memoria) a través de un sitio web manipulado, también conocida como "Microsoft Edge 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 exists within the implementation of CBaseScriptable::PrivateQueryInterface. By performing certain operations in script, an attacker can cause Microsoft Edge to read uninitialized data from a memory location on the stack. An attacker can leverage this to execute code under the context of the current process.
