Severity Rating: Moderate
Revision Note: V1.0 (November 11, 2014): Bulletin published.
Summary: This security update resolves a privately reported vulnerability in Microsoft Input Method Editor (IME) (Japanese). The vulnerability could allow sandbox escape based on the application sandbox policy on a system where an affected version of the Microsoft IME (Japanese) is installed. An attacker who successfully exploited this vulnerability could escape the sandbox of a vulnerable application and gain access to the affected system with logged-in user rights. If the affected system is logged in with administrative rights, an attacker could then install programs; view, change or delete data; or create new accounts with full administrative rights.

Severity Rating: Critical

Summary: This security update resolves a privately reported vulnerability in the Microsoft Secure Channel (Schannel) security package in Windows. The vulnerability could allow remote code execution if an attacker sends specially crafted packets to a Windows server.

Severity Rating: Critical
Revision Note: V1.0 (November 11, 2014): Bulletin published.
Summary: This security update resolves two privately reported vulnerabilities in Microsoft Windows Object Linking and Embedding (OLE). The vulnerabilities could allow remote code execution if a user opens a Microsoft Office file that contains a specially crafted OLE object. An attacker who successfully exploited the vulnerabilities could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Customers whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

Severity Rating: Critical
Revision Note: V1.0 (November 11, 2014): Bulletin published.
Summary: This security update resolves seventeen privately reported vulnerabilities in Internet Explorer. The most severe of these vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. An attacker who successfully exploited these vulnerabilities could gain the same user rights as the current user. Customers whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.

Severity Rating: Critical
Revision Note: V1.0 (November 11, 2014): Bulletin published.
Summary: This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if a logged-on user visits a specially crafted website that is designed to invoke Microsoft XML Core Services (MSXML) through Internet Explorer. In all cases, however, an attacker would have no way to force users to visit such websites. Instead, an attacker would have to convince users to visit a website, typically by getting them to click a link in an email message or in an Instant Messenger request that takes users to the attacker’s website.
