|MS15-126||Cumulative Security Update for JScript and VBScript to Address Remote Code Execution (3116178)||VBScript 5.7||Critical||09-12-2015|
Brief overview of the risk:
This security update resolves vulnerabilities in the VBScript scripting engine in Microsoft Windows. The more severe of the vulnerabilities could allow remote code execution if an attacker hosts a specially crafted website that is designed to exploit the vulnerabilities through Internet Explorer (or leverages a compromised website or a website that accepts or hosts user-provided content or advertisements) and then convinces 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 uses the Internet Explorer rendering engine to direct the user to the specially crafted website.
Detailed Information on the risk:
An information disclosure vulnerability exists when VBScript improperly discloses the contents of its memory, which could provide an attacker with information to further compromise the user’s computer or data.
To exploit the vulnerability, an attacker must know the memory address of where the object was created. The update addresses the vulnerability by changing the way certain functions handle objects in memory.Further information on this exploit is available at : MS15-126
