Severity Rating: CriticalRevision Note: V1.0 (January 12, 2016): Bulletin published.Summary: This security update resolves a vulnerability in the VBScript scripting engine in Microsoft Windows. The vulnerability could allow remote code execution if a user visits a specially crafted website. An attacker who successfully exploited this vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Source: ms-security

Revision Note: V1.0 (January 12, 2016): Advisory published.Summary: Microsoft is announcing a policy change to the Microsoft Root Certificate Program. The new policy no longer allows root certificate authorities to issue X.509 certificates using the SHA-1 hashing algorithm for the purposes of SSL and code signing as of January 1, 2016. Using the SHA-1 hashing algorithm in digital certificates could allow an attacker to spoof content, perform phishing attacks, or perform man-in-the-middle attacks. Source: ms-security
