MS13-095: Vulnerability in XML Digital Signatures Could Allow Denial of Service ( )

Microsoft Security Advisory ( ): Vulnerability in DirectAccess Could Allow Security Feature Bypass - Microsoft is announcing the availability of an update for all supported releases of Windows to address a vulnerability in how DirectAccess authenticates DirectAccess server connections to DirectAccess clients. - An attacker who successfully exploited the vulnerability could use a specially crafted DirectAccess server to pose as a legitimate DirectAccess Server in order to establish connections with legitimate DirectAccess clients. The attacker-controlled system, appearing to be a legitimate server, could cause a client system to automatically authenticate and connect with the attacker-controlled system, allowing the attacker to intercept the target user's network traffic and potentially determine their encrypted domain credentials. Microsoft is not aware of any active attacks that are exploiting this vulnerability as of the release of this advisory. Recommendation: Microsoft recommends that customers apply the update immediately using update management software, or by checking for updates using the Microsoft Update service.

New Microsoft Security Advisories Microsoft Security Advisory ( ): Update for Disabling RC4 - Microsoft is announcing the availability of an update for supported editions of Windows 7, Windows Server 2008 R2, Windows 8, Windows Server 2012 and Windows RT to address known weaknesses in RC4. The update supports the removal of RC4 as an available cipher on affected systems through registry settings. It also allows developers to remove RC4 in individual applications through the use of the SCH_USE_STRONG_CRYPTO flag in the SCHANNEL_CRED structure. These options are not enabled by default. Recommendation: Microsoft recommends that customers download and install the update immediately and then test the new settings in their environments. Please see the Suggested Actions section of this advisory for more information.

New Microsoft Security Advisories Microsoft Security Advisory ( ): Deprecation of SHA-1 Hashing Algorithm for Microsoft Root Certificate Program - Microsoft is announcing a policy change to the Microsoft Root Certificate Program. The new policy will no longer allow root certificate authorities to issue X.509 certificates using the SHA- 1 hashing algorithm for the purposes of SSL and code signing after January 1, 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. Recommendation: Microsoft recommends that certificate authorities no longer sign newly generated certificates using the SHA-1 hashing algorithm and begin migrating to SHA-2. Microsoft also recommends that customers replace their SHA-1 certificates with SHA-2 certificates at the earliest opportunity. Please see the Suggested Actions section of this advisory for more information.

Updated Microsoft Security Advisories Microsoft Security Advisory ( ): Update for Vulnerabilities in Adobe Flash Player in Internet Explorer - On November 12, 2013, Microsoft released an update ( ) for Internet Explorer 10 on all supported editions of Windows 8, Windows Server 2012 and Windows RT, and for Internet Explorer 11 on Windows 8.1, Windows RT 8.1 and Windows Server 2012 R2. The update addresses the vulnerabilities described in Adobe Security bulletin APSB For more information about this update, including download links, see Microsoft Knowledge Base Article APSB13-26 Notes: The update for Windows RT is available via Windows Update only. The update is also available for Internet Explorer 11 Preview in Windows 8.1 Preview and Windows RT 8.1 Preview releases. The update is available via Windows Update.

Updated Microsoft Security Advisories Microsoft Security Advisory ( ): Updates to Improve Cryptography and Digital Certificate Handling in Windows - Microsoft released an update ( ) for all supported editions of Windows 7, Windows Server 2008 R2, Windows 8, Windows Server 2012, and Windows RT to address known weaknesses in RC4. The update supports the removal of RC4 as an available cipher on affected systems through registry settings. It also allows developers to remove RC4 in individual applications through the use of the SCH_USE_STRONG_CRYPTO flag in the SCHANNEL_CRED structure. These options are not enabled by default. After applying the update, Microsoft recommends that customers test any new settings for disabling RC4 prior to implementing them in their environments. For more information, see Microsoft Security Advisory Microsoft announced a policy change to the Microsoft Root Certificate Program for the deprecation of the SHA-1 hashing algorithm in X.509 digital certificates.
