Today Microsoft released 17 bulletins to address 64 security vulnerabilities. The bulletins address vulnerabilities in Windows, Office, Internet Explorer, Visual Studio, .NET Framework and GDI+. Microsoft coordinated with 21 different researchers on the disclosure of these vulnerabilities.
Wolfgang Kandek, Qualys CTO, comments: "Nine bulletins are rated critical and eight bulletins are rated important. All Windows operating systems and all versions of Office are affected, so this is a full plate for system administrators of companies both large and small."
Cumulative security update for Internet Explorer
This security update resolves four privately reported vulnerabilities and one publicly disclosed vulnerability in Internet Explorer. This security update is rated Critical for Internet Explorer 6, Internet Explorer 7, and Internet Explorer 8 on Windows clients; and Moderate for Internet Explorer 6, Internet Explorer 7, and Internet Explorer 8 on Windows servers. Internet Explorer 9 is not affected by the vulnerabilities.
The most severe vulnerabilities could allow remote code execution if a user views a specially crafted Web page using Internet Explorer. An attacker who successfully exploited any of these vulnerabilities could gain the same user rights as the local user. 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.
Vulnerabilities in SMB client could allow remote code execution
This security update resolves one publicly disclosed vulnerability and one privately reported vulnerability 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 specially crafted SMB server.
Vulnerability in SMB server could allow remote code execution
This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability 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.
Cumulative security update of ActiveX Kill Bits
This security update resolves two privately reported vulnerabilities and one publicly disclosed vulnerability in Microsoft software. The vulnerabilities could allow remote code execution if a user views a specially crafted Web page that instantiates a specific ActiveX control with Internet Explorer. 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 update also includes kill bits for three third-party ActiveX controls.
Vulnerability in .NET framework could allow remote code execution
This security update resolves a publicly disclosed vulnerability in Microsoft .NET Framework. The vulnerability could allow remote code execution on a client system if a user views a specially crafted Web page using a Web browser that can run XAML Browser Applications (XBAPs). 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. The vulnerability could also allow remote code execution on a server system running IIS, if that server allows processing ASP.NET pages and an attacker succeeds in uploading a specially crafted ASP.NET page to that server and then executes the page, as could be the case in a Web hosting scenario. This vulnerability could also be used by Windows .NET applications to bypass Code Access Security (CAS) restrictions.
Vulnerability in GDI+ could allow remote code execution
This security update resolves a privately reported vulnerability in Microsoft Windows GDI+. The vulnerability could allow remote code execution if a user viewed a specially crafted image file using affected software or browsed a Web site that contains specially crafted content. 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.
Vulnerability in DNS resolution could allow remote code execution
This security update resolves a privately reported vulnerability in Windows DNS resolution. The vulnerability could allow remote code execution if an attacker gained access to the network and then created a custom program to send specially crafted LLMNR broadcast queries to the target systems. Firewall best practices and standard default firewall configurations can help protect networks from attacks that originate outside the enterprise perimeter. Best practices recommend that systems that are connected to the Internet have a minimal number of ports exposed. In this case, the LLMNR ports should be blocked from the Internet.
Vulnerability in JScript and VBScript scripting engines could allow remote code execution
This security update resolves a privately reported vulnerability in the JScript and VBScript scripting engines. The vulnerability could allow remote code execution if a user visited a specially crafted Web site. An attacker would have no way to force users to visit the Web site. Instead, an attacker would have to convince users to visit the Web site, typically by getting them to click a link in an e-mail message or Instant Messenger message that takes users to the attacker's Web site.
Vulnerability in the OpenType Compact Font Format (CFF) driver could allow remote code execution
This security update resolves a privately reported vulnerability in the OpenType Compact Font Format (CFF) driver. The vulnerability could allow remote code execution if a user views content rendered in a specially crafted CFF font. In all cases, an attacker would have no way to force users to view the specially crafted content. Instead, an attacker would have to convince users to visit a Web site, typically by getting them to click a link in an e-mail message or Instant Messenger message that takes users to the attacker's Web site.
Vulnerabilities in Microsoft Excel could allow remote code execution
This security update resolves three privately reported vulnerabilities in Microsoft PowerPoint. The vulnerabilities could allow remote code execution if a user opens a specially crafted PowerPoint file. An attacker who successfully exploited any of these vulnerabilities could gain the same user rights as the local user. 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.
Vulnerabilities in Microsoft Office could allow remote code execution
This security update resolves one publicly disclosed vulnerability and one privately reported vulnerability in Microsoft Office. The vulnerabilities could allow remote code execution if a user opens a specially crafted Office file or if a user opens a legitimate Office file that is located in the same network directory as a specially crafted library file. An attacker who successfully exploited either of these vulnerabilities could gain the same user rights as the logged on user. 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.
Vulnerability in Windows Fax Cover Page Editor could allow remote code execution
This security update resolves one publicly disclosed vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if a user opened a specially crafted fax cover page file (.cov) using the Windows Fax Cover Page Editor. An attacker who successfully exploited this vulnerability could gain the same user rights as the logged-on user. 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.
Vulnerability in Microsoft Foundation Class (MFC) Library could allow remote code execution
This security update resolves a publicly disclosed vulnerability in certain applications built using the Microsoft Foundation Class (MFC) Library. The vulnerability could allow remote code execution if a user opens a legitimate file associated with such an affected application, and the file is located in the same network folder as a specially crafted library file. For an attack to be successful, a user must visit an untrusted remote file system location or WebDAV share and open a document from this location that is then loaded by the affected application.
Vulnerability in MHTML could allow information disclosure
This security update resolves a publicly disclosed vulnerability in the MHTML protocol handler in Microsoft Windows. The vulnerability could allow information disclosure if a user visited a specially crafted Web site. In a Web-based attack scenario, a Web site could contain a specially crafted link that is used to exploit this vulnerability.
