Severity Rating: Critical
Revision Note: V1.0 (December 8, 2015): Bulletin published.
Summary: 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.

3123040 – Inadvertently Disclosed Digital Certificate Could Allow Spoofing – Version: 1.0
Revision Note: V1.0 (December 8, 2015): Advisory published.
Summary: Microsoft is aware of an SSL/TLS digital certificate for *.xboxlive.com for which the private keys were inadvertently disclosed. The certificate could be used in attempts to perform man-in-the-middle attacks. It cannot be used to issue other certificates, impersonate other domains, or sign code. This issue affects all supported releases of Microsoft Windows. Microsoft is not currently aware of attacks related to this issue.
MS15-129 – Critical: Security Update for Silverlight to Address Remote Code Execution (3106614) – Version: 1.0
Severity Rating: Critical
Revision Note: V1.0 (December 8, 2015): Click here to enter text.
Summary: This security update resolves vulnerabilities in Microsoft Silverlight. The most severe of the vulnerabilities could allow remote code execution if Microsoft Silverlight incorrectly handles certain open and close requests that could result in read- and write-access violations. To exploit the vulnerability, an attacker could host a website that contains a specially crafted Silverlight application and then convince a user to visit a compromised website. The attacker could also take advantage of websites containing specially crafted content, including those that accept or host user-provided content or advertisements.
MS15-133 – Important: Security Update for Windows PGM to Address Elevation of Privilege (3116130) – Version: 1.0
Severity Rating: Important
Revision Note: V1.0 (December 8, 2015): Bulletin published.
Summary: This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow elevation of privilege if an attacker logs on to a target system and runs a specially crafted application that, by way of a race condition, results in references to memory locations that have already been freed. Microsoft Message Queuing (MSMQ) must be installed and the Windows Pragmatic General Multicast (PGM) protocol specifically enabled for a system to be vulnerable. MSMQ is not present in default configurations and, if it is installed, the PGM protocol is available but disabled by default.
