Microsoft Security Updates February 2010

Microsoft has released a total of 14 security updates on yesterday’s patch day. The updates are, as usual, for several Microsoft software products including the Microsoft Windows operating system and Microsoft Office.

Five of the updates have received a critical rating by Microsoft, the highest security rating. Seven were ranked as important which is the second highest rating and one as moderate. The security ratings can vary depending on the operating system and Office version used.

Microsoft Windows 7 users for instance will notice that the security updates have all received an important rating for their operating system while Windows 2000 or Windows XP users will notice that their operating systems have received the largest amount of critical ratings.

• Microsoft Security Bulletin MS10-006 – Critical – Vulnerabilities in SMB Client Could Allow Remote Code Execution (978251) – his security update resolves two privately reported vulnerabilities in Microsoft Windows. The vulnerabilities could allow remote code execution if an attacker sent a specially crafted SMB response to a client-initiated SMB request. To exploit these vulnerabilities, an attacker must convince the user to initiate an SMB connection to a malicious SMB server.
  This security update is rated Critical for Microsoft Windows 2000, Windows XP, Windows Server 2003, Windows 7, and Windows Server 2008 R2, and is rated Important for Windows Vista and Windows Server 2008.
• Microsoft Security Bulletin MS10-007 – Critical – Vulnerability in Windows Shell Handler Could Allow Remote Code Execution (975713) – This security update resolves a privately reported vulnerability in Microsoft Windows 2000, Windows XP, and Windows Server 2003. Other versions of Windows are not impacted by this security update. The vulnerability could allow remote code execution if an application, such as a Web browser, passes specially crafted data to the ShellExecute API function through the Windows Shell Handler.
  This security update is rated Critical for all supported editions of Microsoft Windows 2000, Windows XP, and Windows Server 2003
• Microsoft Security Bulletin MS10-008 – Critical – Cumulative Security Update of ActiveX Kill Bits (978262) – his security update addresses a privately reported vulnerability for Microsoft software.

• Microsoft Security Bulletin MS10-009 – Critical – Vulnerabilities in Windows TCP/IP Could Allow Remote Code Execution (974145) – his security update resolves four privately reported vulnerabilities in Microsoft Windows. The most severe of these vulnerabilities could allow remote code execution if specially crafted packets are sent to a computer with IPv6 enabled. An attacker could try to exploit the vulnerability by creating specially crafted ICMPv6 packets and sending the packets to a system with IPv6 enabled. This vulnerability may only be exploited if the attacker is on-link.
  This security update is rated Critical for Windows Vista and Windows Server 2008.
• Microsoft Security Bulletin MS10-013 – Critical – Vulnerability in Microsoft DirectShow Could Allow Remote Code Execution (977935) – This security update resolves a privately reported vulnerability in Microsoft DirectShow. The vulnerability could allow remote code execution if a user opened a specially crafted AVI file. 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. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
  This security update is rated Critical for all supported editions of Microsoft Windows except for all supported Itanium-based editions of Windows Server 2003, Windows Server 2008, and Windows Server 2008 R2, for which this security update is rated Important.
• Microsoft Security Bulletin MS10-003 – Important – Vulnerability in Microsoft Office (MSO) Could Allow Remote Code Execution (978214) – This security update resolves a privately reported vulnerability in Microsoft Office that could allow remote code execution if a user opens a specially crafted Office file. 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. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
  This security update is rated Important for all supported editions of Microsoft Office XP and Microsoft Office 2004 for Mac.
• Microsoft Security Bulletin MS10-004 – Important – Vulnerabilities in Microsoft Office PowerPoint Could Allow Remote Code Execution (975416) – This security update resolves six privately reported vulnerabilities in Microsoft Office PowerPoint. The vulnerabilities could allow remote code execution if a user opens a specially crafted PowerPoint file. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
  This security update is rated Important for supported editions of Microsoft Office PowerPoint 2002 and Microsoft Office PowerPoint 2003, and Microsoft Office 2004 for Mac
• Microsoft Security Bulletin MS10-010 – Important – Vulnerability in Windows Server 2008 Hyper-V Could Allow Denial of Service (977894) – his security update resolves a privately reported vulnerability in Windows Server 2008 Hyper-V and Windows Server 2008 R2 Hyper-V. The vulnerability could allow denial of service if a malformed sequence of machine instructions is run by an authenticated user in one of the guest virtual machines hosted by the Hyper-V server. An attacker must have valid logon credentials and be able to log on locally into a guest virtual machine to exploit this vulnerability. The vulnerability could not be exploited remotely or by anonymous users.
  This security update is rated Important for all supported x64-based editions of Windows Server 2008 and Windows Server 2008 R2
• Microsoft Security Bulletin MS10-011 – Important – Vulnerability in Windows Client/Server Run-time Subsystem Could Allow Elevation of Privilege (978037) – This security update resolves a privately reported vulnerability in Microsoft Windows Client/Server Run-time Subsystem (CSRSS) in Microsoft Windows 2000, Windows XP, and Windows Server 2003. Other versions of Windows are not affected. The vulnerability could allow elevation of privilege if an attacker logs on to the system and starts a specially crafted application designed to continue running after the attacker logs out. An attacker must have valid logon credentials and be able to log on locally to exploit this vulnerability. The vulnerability could not be exploited by anonymous users.
  This security update is rated Important for all supported editions of Microsoft Windows 2000, Windows XP, and Windows Server 2003.
• Microsoft Security Bulletin MS10-012 – Important – Vulnerabilities in SMB Server Could Allow Remote Code Execution (971468) – This security update resolves several privately reported vulnerabilities in Microsoft Windows. The most severe of these vulnerabilities could allow remote code execution if an attacker created a specially crafted SMB packet and sent the packet to an affected system. Firewall best practices and standard default firewall configurations can help protect networks from attacks originating outside the enterprise perimeter that would attempt to exploit these vulnerabilities.
  This security update is rated Important for all supported editions of Microsoft Windows.
• Microsoft Security Bulletin MS10-014 – Important – Vulnerability in Kerberos Could Allow Denial of Service (977290) – This security update resolves a privately reported vulnerability in Microsoft Windows.

   I would NOT recommend downloading this security update until Microsoft fixes it. It WILL cause your computer to crash. I know it made mine crash (running Vista Home Premium).
