MS16-012 – Critical: Security Update for Microsoft Windows PDF Library to Address Remote Code Execution (3138938) – Version: 1.0

Severity Rating: Critical
Revision Note: V1.0 (February 9, 2016): Bulletin published.
Summary: This security update resolves vulnerabilities in Microsoft Windows. The more severe of the vulnerabilities could allow remote code execution if Microsoft Windows PDF Library improperly handles application programming interface (API) calls, which could allow an attacker to run arbitrary code on the user’s system. An attacker who successfully exploited the 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. However, an attacker would have no way to force users to download or open a malicious PDF document.

3109853 – Update to Improve TLS Session Resumption Interoperability – Version: 1.0

Revision Note: V1.0 (January 12, 2016): Advisory published.
Summary: Microsoft is announcing the availability of an update to improve interoperability between Schannel-based TLS clients and 3rd-party TLS servers that enable RFC5077-based resumption and that send the NewSessionTicket message in the abbreviated TLS handshake. The update addresses an issue in schannel.dll that could cause RFC5077 session ticket-based resumption to fail and subsequently cause WinInet-based clients (for example, Internet Explorer and Microsoft Edge) to perform a fallback to a lower TLS protocol version than the one that would have been negotiated otherwise. This improvement is part of ongoing efforts to bolster the effectiveness of encryption in Windows.

MS16-001 – Critical: Cumulative Security Update for Internet Explorer (3124903) – Version: 1.0

Severity Rating: Critical
Revision Note: V1.0 (January 12, 2016): Bulletin published.
Summary: This security update resolves vulnerabilities in Internet Explorer. The more severe of the vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. 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 control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

3123479 – Deprecation of SHA-1 Hashing Algorithm for Microsoft Root Certificate Program – Version: 1.0

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.
