Vulnerability Summary for the Week of August 9, 2010

Revision Note: V3.1 (August 11, 2010): Removed Windows Movie Maker 2.6 as an affected component on Windows 7 for MS10-016.Summary: This bulletin summary lists security bulletins released for March 2010.

Revision Note: V2.0 (August 10, 2010): Advisory updated to reflect publication of security bulletin.Summary: Microsoft has completed the investigation into a public report of this vulnerability. We have issued MS10-049 to address this issue. For more information about this issue, including download links for an available security update, please review MS10-049. The vulnerability addressed is the TLS/SSL Renegotiation Vulnerability - CVE-2009-3555. For additional information on this advisory, see Microsoft Knowledge Base Article 977377.

Severity Rating: Critical - Revision Note: V1.0 (August 10, 2010): Bulletin published.Summary: This security update resolves two privately reported vulnerabilities in Microsoft .NET Framework and Microsoft Silverlight. The vulnerabilities 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) or Silverlight applications, or if an attacker succeeds in convincing a user to run a specially crafted Microsoft .NET application. 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 vulnerabilities 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 executing the page, as could be the case in a Web hosting scenario.

Severity Rating: Important - Revision Note: V1.0 (August 10, 2010): Bulletin published.Summary: This security update resolves one publicly disclosed vulnerability and one privately reported vulnerability in the Tracing Feature for Services. The vulnerabilities could allow elevation of privilege if an attacker runs a specially crafted application. An attacker must have valid logon credentials and be able to log on locally to exploit this vulnerability. The vulnerability could not be exploited remotely or by anonymous users.

Severity Rating: Important - Revision Note: V1.0 (August 10, 2010): Bulletin published.Summary: This security update resolves two privately reported vulnerabilities in Microsoft Windows. The more severe of these vulnerabilities could allow elevation of privilege due to an error in the processing of a specific input buffer. An attacker who is able to log on to the target system could exploit this vulnerability and run arbitrary code with system-level privileges. The attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

Severity Rating: Important - Revision Note: V1.0 (August 10, 2010): Bulletin published.Summary: This security update resolves a privately reported vulnerability in Microsoft Office. The vulnerability could allow remote code execution if a user opens a specially crafted Excel file. 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.

Severity Rating: Critical - Revision Note: V1.0 (August 10, 2010): Bulletin published.Summary: This security update resolves four privately reported vulnerabilities in Microsoft Office. The most severe vulnerabilities could allow remote code execution if a user opens or previews a specially crafted RTF e-mail message. 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.

Severity Rating: Critical - Revision Note: V1.0 (August 10, 2010): Bulletin published.Summary: This security update resolves a privately reported vulnerability in Cinepak Codec. The vulnerability could allow remote code execution if a user opens a specially crafted media file or receives specially crafted streaming content from a Web site or any application that delivers Web content. An attacker who successfully exploited this vulnerability 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.

Severity Rating: Critical - Revision Note: V1.0 (August 10, 2010): Bulletin published.Summary: 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.

Severity Rating: Critical - Revision Note: V1.0 (August 10, 2010): Bulletin published.Summary: This security update resolves six privately reported vulnerabilities in Internet Explorer. The most severe vulnerabilities could allow remote code execution if a user views a specially crafted Web page using 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.

Severity Rating: Critical - Revision Note: V1.0 (August 10, 2010): Bulletin published.Summary: This security update resolves a privately reported vulnerability in Microsoft MPEG Layer-3 audio codecs. The vulnerability could allow remote code execution if a user opens a specially crafted media file or receives specially crafted streaming content from a Web site or any application that delivers Web content. An attacker who successfully exploited this vulnerability 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.

Severity Rating: Critical - Revision Note: V1.0 (August 10, 2010): Bulletin published.Summary: This security update resolves a privately reported vulnerability in Microsoft XML Core Services. The vulnerability could allow remote code execution if a user viewed a specially crafted Web page using Internet Explorer. An attacker would have no way to force users to visit these Web sites. Instead, an attacker would have to persuade 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.

Severity Rating: Important - Revision Note: V1.0 (August 10, 2010): Bulletin published.Summary: This security update resolves a privately reported vulnerability in Windows Movie Maker. The vulnerability could allow remote code execution if an attacker sent a specially crafted Movie Maker project file and convinced the user to open the specially crafted file. 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.

Severity Rating: Critical - Revision Note: V1.0 (August 10, 2010): Bulletin published.Summary: This security update resolves one publicly disclosed vulnerability and one privately reported vulnerability in the Secure Channel (SChannel) security package in Windows. The more severe of these vulnerabilities could allow remote code execution if a user visits a specially crafted Web site that is designed to exploit these vulnerabilities through an Internet Web browser. In all cases, however, an attacker would have no way to force users to visit these Web sites. 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 in an Instant Messenger message that takes users to the attacker's Web site.

Severity Rating: Important - Revision Note: V1.0 (August 10, 2010): Bulletin published.Summary: This security update resolves one publicly disclosed and four privately reported vulnerabilities in the Windows kernel-mode drivers. The most severe of these vulnerabilities could allow elevation of privilege if an attacker logs on to an affected system and runs a specially crafted application. An attacker must have valid logon credentials and be able to log on locally to exploit this vulnerability. The vulnerability could not be exploited remotely or by anonymous users.
