March 2015 - Microsoft Releases 14 Security Advisories

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.

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.

This security update resolves 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.

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 the 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.

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.

This security update resolves vulnerabilities in Microsoft Windows. The most severe of the vulnerabilities could allow elevation of privilege 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.

This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow information disclosure if an attacker convinces a user to visit a website that contains specially crafted PNG images.

This security update resolves vulnerabilities in Microsoft Windows. The most severe of 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 the vulnerability could run arbitrary code in the security context of the account of another user who is logged on to the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts potentially with full user rights.

This security update resolves vulnerabilities in Microsoft Exchange Server. The most severe of the vulnerabilities could allow elevation of privilege if a user clicks a specially crafted URL that takes them to a targeted Outlook Web App site. An attacker would have no way to force users to visit a specially crafted website. Instead, an attacker would have to convince them to visit the website, typically by getting them to click a link in an instant messenger or email message that takes them to the attacker's website, and then convince them to click the specially crafted URL.

This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow spoofing if an attacker who is logged onto a domain-joined system runs a specially crafted application that could establish a connection with other domain-joined systems as the impersonated user or system. The attacker must be logged onto a domain-joined system and be able to observe network traffic.

This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow a user with limited privileges on an affected system to leverage Task Scheduler to execute files that they do not have permissions to run. An attacker who successfully exploited this vulnerability could bypass ACL checks and run privileged executables.

This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow information disclosure if a user browses to a website containing a specially crafted JPEG XR (.JXR) image. This vulnerability would not allow an attacker to execute code or to elevate their user rights directly, but it could be used to obtain information that could be used to try to further compromise the affected system.

This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow denial of service if an attacker creates multiple Remote Desktop Protocol (RDP) sessions that fail to properly free objects in memory. By default, RDP is not enabled on any Windows operating system. Systems that do not have RDP enabled are not at risk.

This security update resolves a vulnerability in Microsoft Windows that facilitates exploitation of the publicly disclosed FREAK technique, an industry-wide issue that is not specific to Windows operating systems. The vulnerability could allow a man-in-the-middle (MiTM) attacker to force the downgrading of the key length of an RSA key to EXPORT-grade length in a TLS connection. Any Windows system using Schannel to connect to a remote TLS server with an insecure cipher suite is affected.
