Microsoft fixes 17 flaws in 11 patches; 6 are 'critical'

Most of the patches deemed "critical" affect Microsoft Office, and include Office for Mac.

Microsoft on Tuesday released its February 2008 security bulletin, which includes 11 bulletins, six of which are deemed "critical" by Microsoft, while five are deemed "important." One bulletin, suggested in the advance notice posted Thursday, failed to be released Tuesday. A majority of the "critical" patches affect Microsoft Office, two critical patches include users of Office for Mac 2004, one affects Visual Basic 6.

The "important" patches are mostly Internet services-related. One patch is specific to the Windows Vista update, however, all the Windows Vista-related updates will be included with Windows Vista SP1, expected to roll out to consumers in mid-to-late March.

Tim Rains, security response communications lead for Microsoft, humorously noted that "Windows Vista SP1 and Windows Server 2008 are not affected by any of today's bulletins." They're not affected because they are not yet available to the public. All Microsoft security patches for both Windows and Office software are available via Microsoft Update or via the individual bulletins detailed below.

MS08-003: Important

Titled "Vulnerability in Active Directory Could Allow Denial of Service (946538)," this bulletin affects users of Microsoft Windows 2000, XP SP2, Server 2003, but does not affect Windows Vista. A vulnerability detailed in CVE-2008-0088 exists in implementations of Active Directory on Microsoft Windows 2000 Server and Windows Server 2003 and Active Directory Application Mode (ADAM). Microsoft says "attacker must have valid log-on credentials to exploit this vulnerability. An attacker who successfully exploited this vulnerability could cause the system to stop responding or automatically restart."

MS08-004: Important

Titled "Vulnerability in Windows TCP/IP Could Allow Denial of Service (946456)," this bulletin only affects users of Windows Vista. The update addresses the vulnerability detailed in CVE-2008-0084 that exists in Transmission Control Protocol/Internet Protocol (TCP/IP) processing. Microsoft says "an attacker who successfully exploited this vulnerability could cause the affected system to stop responding and automatically restart."

MS08-005: Important

Titled "Vulnerability in Internet Information Services Could Allow Elevation of Privilege (942831)," this bulletin affects users of Microsoft Windows 2000, XP SP2, Server 2003, and Vista. The update addresses the vulnerability detailed in CVE-2008-0074 that exists in Internet Information Services (IIS). Microsoft says "a local 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. 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."

MS08-006: Important

Titled "Vulnerability in Internet Information Services Could Allow Remote Code Execution (942830)," this bulletin affects users of Microsoft Windows XP SP2 and Server 2003, but not Windows 2000 or Vista. The update addresses the vulnerability detailed in CVE-2008-0075 that exists in the way that IIS handles input to ASP Web pages. Microsoft says "An attacker who successfully exploited this vulnerability could then perform actions on the IIS server with the same rights as the Worker Process Identity (WPI). The WPI is configured with Network Service account privileges by default. IIS servers with ASP pages whose application pools are configured with a WPI that uses an account with administrative privileges could be more seriously impacted than IIS servers whose application pool is configured with the default WPI settings."

MS08-007: Critical

Titled "Vulnerability in WebDAV Mini-Redirector Could Allow Remote Code Execution (946026)," this bulletin affects users of Microsoft Windows XP SP2, Server 2003, and Vista, but not Windows 2000. This update addresses the vulnerability detailed in CVE-2008-0080 in the WebDAV Mini-Redirector. Microsoft says "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."

MS08-008: Critical

Titled "Vulnerability in OLE Automation Could Allow Remote Code Execution (947890)," this bulletin affects users of all supported editions of Microsoft Windows 2000, Windows XP, Windows Vista, Microsoft Office 2004 for Mac, and Visual Basic 6. The update addresses the vulnerability detailed in CVE-2007-0065. If exploited, the vulnerability could allow remote code execution through attacks on Object Linking and Embedding (OLE) Automation if a user viewed a specially crafted Web page.

The update addresses the vulnerability detailed in CVE-2008-0109 and could allow remote code execution if a user opens a specially crafted Word file. Microsoft says "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.
