Revision Note: V1.0 (April 14, 2015): Bulletin published.
Summary: This security update resolves vulnerabilities in Microsoft Office server and productivity software. The vulnerabilities could allow elevation of privilege if an attacker sends a specially crafted request to an affected SharePoint server. An attacker who successfully exploited the vulnerabilities could read content that the attacker is not authorized to read, use the victim’s identity to take actions on the SharePoint site on behalf of the victim, such as change permissions and delete content, and inject malicious content in the browser of the victim.

Revision Note: V1.0 (March 24, 2015): Advisory published.
Summary: Microsoft is aware of improperly issued digital certificates coming from the subordinate CA, MCS Holdings, which could be used in attempts to spoof content, perform phishing attacks, or perform man-in-the-middle attacks. The improperly issued certificates cannot be used to issue other certificates, impersonate other domains, or sign code. This issue affects all supported releases of Microsoft Windows.

Revision Note: V1.0 (March 16, 2015): Advisory published.
Summary: Microsoft is aware of an improperly issued SSL certificate for the domain “live.fi” that could be used in attempts to spoof content, perform phishing attacks, or perform man-in-the-middle attacks. This issue affects all supported releases of Microsoft Windows. Microsoft is not currently aware of attacks related to this issue.

Revision Note: V1.0 (March 10, 2015): Bulletin published.
Summary: This security update resolves four privately reported vulnerabilities in Microsoft Windows. The most severe of these vulnerabilities could allow security feature bypass if an attacker logs on to the system and runs a specially crafted application designed to increase privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full administrative rights.

Severity Rating: Critical
Revision Note: V1.0 (March 10, 2015): Bulletin published.
Summary: This security update resolves vulnerabilities in Microsoft Office. The most severe of the vulnerabilities could allow remote code execution if a user opens a specially crafted Microsoft Office file. An attacker who successfully exploited the vulnerabilities could run arbitrary code in the context of 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: Important
Revision Note: V1.0 (March 10, 2015): Bulletin published.
Summary: This security update resolves two privately reported vulnerabilities in Microsoft Windows. The vulnerabilities could allow elevation of privilege if an attacker logs on to an affected system and runs a specially crafted application. An attacker who successfully exploited this vulnerability could run arbitrary code in the security context of the local system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

Severity Rating: Critical
Revision Note: V1.0 (March 10, 2015): Bulletin published.
Summary: This security update resolves vulnerabilities in Internet Explorer. The most 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 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: V1.1 (March 10, 2015): Bulletin revised to better explain the attack vector for the DLL Planting Remote Code Execution Vulnerability (CVE-2015-0096).
Summary: This security update resolves two privately reported vulnerabilities in Microsoft Windows. The vulnerabilities could allow remote code execution if an attacker successfully convinces a user to browse to a specially crafted website, open a specially crafted file, or open a file in a working directory that contains a specially crafted DLL file.

Severity Rating: Critical
Revision Note: V1.0 (March 10, 2015): Bulletin published.
Summary: This security update resolves vulnerabilities in Microsoft Windows. The most severe of the vulnerabilities could allow remote code execution if a user views a specially crafted file or website. An attacker who successfully exploited these vulnerabilities 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 these vulnerabilities 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. 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: Important
Revision Note: V1.0 (March 10, 2015): Bulletin published.
Summary: This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow Security Feature Bypass if a user runs a specially crafted application that is designed to cause Task Scheduler to improperly validate impersonation-level security.
