The VBScript engine in Microsoft Edge allows remote attackers to obtain sensitive information from process memory via a crafted web site, aka "Scripting Engine Information Disclosure Vulnerability."

El motor VBScript en Microsoft Edge permite a atacantes remotos obtener información sensible de la memoria de proceso a través de un sitio web manipulado, también conocida como "Scripting Engine Information Disclosure Vulnerability".

This vulnerability allows remote attackers to leak sensitive information on vulnerable installations of Microsoft Chakra. 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 handling of ArrayBuffer.transfer. The issue lies in the failure to properly initialize a buffer prior to returning it to the user. An attacker can leverage this vulnerability to leak sensitive information within the context of the current process.
