BACKGROUND\r\n\r\nThe Microsoft Windows kernel controls which processes are allowed to run\r\nand is responsible for accessing hardware such as storage devices and\r\nvideo adapters, scheduling time for each process to execute, managing\r\nmemory, and other system control tasks. For more information on on the\r\nWindows kernel visit MSDN at the URL shown below.\r\n\r\nhttp://msdn.microsoft.com/\r\n\r\nII. DESCRIPTION\r\n\r\nRemote exploitation of a design error in certain kernel GDI functions in\r\nmultiple versions of Microsoft Corp.'s Windows operating system may\r\nallow an attacker to cause a denial of service condition.\r\n\r\nDuring testing of the MS06-001 WMF (Windows Metafile) vulnerability, a\r\nflaw was found in the handling of WMF files. This flaw can cause the\r\nkernel to perform a bug check, also known as a "blue screen" or system\r\ncrash, when it tries to parse the file. The cause of this bug check is\r\nan attempt by a function in a kernel system call to read a value\r\nobtained by dereferencing an offset into a kernel structure. This value\r\nhad been previously created and then reset by previous system calls, and\r\nat the point it is accessed it does not contain a valid memory\r\nreference. This results in an access violation error, which in turn\r\ntriggers the bug check.\r\n\r\nThis vulnerability is different from both the Microsoft MS06-001 WMF\r\nvulnerability and the MS05-053 WMF vulnerability and is not fixed by\r\neither of these patches.\r\n\r\nIII. ANALYSIS\r\n\r\nExploitation of this vulnerability would allow a remote attacker to\r\nperform a denial of service against an affected system.\r\n\r\nDepending on where the file was saved and configuration details of the\r\ntarget, this could result in a persistent denial of service condition,\r\ncausing an immediate reboot upon logging on after an attack. The\r\nresults of testing this vulnerability suggest that in some cases it may\r\ncause corruption of the system in a manner that prevents the system from\r\nrebooting.\r\n\r\nIt is likely that Enhanced Windows Metafiles (EMF) are also affected,\r\nbut this has not yet been confirmed.\r\n\r\nCurrently, due to the type of location being referenced by the kernel,\r\nit appears that the vulnerability may only be exploitable by a remote\r\nattacker to cause a DoS condition. The vectors that could be used to\r\nremotely exploit this vulnerability would most likely be similar to\r\nthose that the MS06-001 vulnerability used.\r\n\r\nIV. DETECTION\r\n\r\nThis vulnerability has been confirmed to affect the following Microsoft\r\nWindows operating systems:\r\n\r\n * Windows XP with Service Pack 2\r\n * Windows 2003 Server\r\n\r\nOther Windows operating systems may also be affected.\r\n\r\nV. WORKAROUND\r\n\r\nBlocking .wmf files at all e-mail and Web gateways is strongly\r\nrecommended. However, this is not effective if blocking is done based\r\non file extensions (e.g., .wmf), as an attacker can simply rename the\r\nfile to a new extension.\r\n\r\nReading e-mail in plain-text can prevent automatic exploitation via\r\nelectronic mail.\r\n\r\nVI. VENDOR RESPONSE\r\n\r\nMicrosoft has addressed this vulnerability within MS07-017. For more\r\ninformation, consult their bulletin at the following URL.\r\n\r\nhttp://www.microsoft.com/technet/security/Bulletin/MS07-017.mspx\r\n\r\nVII.

An attacker who successfully exploited this vulnerability could cause the affected system to stop responding and possibly restart.\r\n\t\r\nMitigating Factors for WMF Denial of Service Vulnerability - CVE-2007-1211:\r\n\u2022\t\r\n\r\nIn a Web-based attack scenario, an attacker would have to host a Web site that contains a Web page that is used to exploit this vulnerability. An attacker would have no way to force users to visit a specially crafted Web site. Instead, an attacker would have to convince them to visit the Web site, typically by getting them to click a link that takes them to the attacker's Web site. After they click the link, they would be prompted to perform several actions. An attack could only occur after they performed these actions.\r\n\u2022\t\r\n\r\nThe vulnerability could be exploited by an attacker who convinced a user to open a specially crafted file or to view a folder that contains the specially crafted image. There is no way for an attacker to force a user to open a specially crafted file, except potentially through previewing an e-mail message.\r\nTop of sectionTop of section\r\n\t\r\nWorkarounds for WMF Denial of Service Vulnerability - CVE-2007-1211:\r\n\r\nMicrosoft has tested the following workarounds. While these workarounds will not correct the underlying vulnerability, they help block known attack vectors. When a workaround reduces functionality, it is identified in the following section.\r\n\u2022\t\r\n\r\nRead e-mail messages in plain text format if you are using Outlook 2002 Service Pack 3 or a later version, or Outlook Express 6 SP1 or a later version, to help protect yourself from the HTML e-mail attack vector.\r\n\r\nCustomers using Microsoft Outlook 2002 Service Pack 3 and Microsoft Outlook Express 6 Service Pack 1 or later versions can enable this setting and view e-mail messages that are not digitally signed or e-mail messages that are not encrypted in plain text only.\r\n\r\nDigitally signed e-mail messages or encrypted e-mail messages are not affected by the setting and may be read in their original formats. For more information about how to enable this setting in Outlook 2002, see Microsoft Knowledge Base Article 307594.\r\n\r\nFor more information about how to enable this setting in Outlook Express 6, see Microsoft Knowledge Base Article 291387.\r\n\r\nImpact of Workaround: E-mail messages that are viewed in plain text format will not contain pictures, specialized fonts, animations, or other rich content.

An attacker who exploited this vulnerability could cause the affectedsystem to stop responding and automatically restart. Note that the denial of service vulnerability would not allow attackers to execute code or elevate their privileges, but it could cause the affected program to stop accepting requests.\r\n\r\nWhat causes the vulnerability?\r\nThe vulnerability is caused by an attempt to read a data value that contains an invalid memory reference.\r\n\r\nWhat is the Windows Metafile (WMF) image formats?\r\nThe WMF image format is a 16-bit metafile format that can contain both vector information and bitmap information. It is optimized for the Windows operating system.\r\n\r\nFor more information about image types and formats, see Microsoft Knowledge Base Article 320314. Additional information about these file formats is also available at the MSDN Library Web Site.\r\n\r\nWhat might an attacker use the vulnerability to do?\r\nAn attacker who successfully exploited this vulnerability could cause the affected system to stop responding and possibly restart.\r\n\r\nWho could exploit the vulnerability?\r\nIn a Web-based attack scenario, an attacker would have to host a Web site that contains a Web page that is used to attempt to exploit this vulnerability. An attacker would have no way to force users to visit a specially crafted Web site. Instead, an attacker would have to convince them to visit the Web site, typically by getting them to click a link that takes them to the attacker's site. It could also be possible to display specially crafted Web content by using banner advertisements or by using other methods to deliver Web content to affected systems.\r\n\r\nHow could an attacker exploit this vulnerability?\r\nThe vulnerability could be exploited on the affected systems by an attacker who persuaded a user to open a specially crafted file or to view a folder that contains the specially crafted image. There is no way for an attacker to force a user to open a specially crafted file, except potentially through previewing an email message.\r\n\r\nWhat systems are primarily at risk from the vulnerability? \r\nWorkstations and terminal servers are primarily at risk. Servers could be at more risk if users who do not have sufficient administrative permissions are given the ability to log on to servers and run programs or browse the Internet. However, best practices strongly discourage allowing this.\r\n\r\nI am running Internet Explorer on Windows Server 2003. Does this mitigate this vulnerability?\r\nYes. By default, Internet Explorer on Windows Server 2003 runs in a restricted mode that is known as Enhanced Security Configuration. This mode sets the security level for the Internet zone to High. This is a mitigating factor for Web sites that have not been added to Internet Explorer Trusted sites zone.\r\n\r\nWhat is the Internet Explorer Enhanced Security Configuration?\r\nInternet Explorer Enhanced Security Configuration is a group of preconfigured Internet Explorer settings that reduce the likelihood of a user or of an administrator downloading and running specially crafted Web content on a server. Internet Explorer Enhanced Security Configuration reduces this risk by modifying many security-related settings. This includes the settings on the Security tab and the Advanced tab in the Internet Options dialog box. Some of the important modifications include the following:\r\n\u2022\t\r\n\r\nSecurity level for the Internet zone is set to High. This setting disables scripts, ActiveX controls, Microsoft Java Virtual Machine (MSJVM), and file downloads.\r\n\u2022\t\r\n\r\nAutomatic detection of intranet sites is disabled. This setting assigns all intranet Web sites and all Universal Naming Convention (UNC) paths that are not explicitly listed in the Local intranet zone to the Internet zone.\r\n\u2022\t\r\n\r\nInstall On Demand and non-Microsoft browser extensions are disabled. This setting prevents Web pages from automatically installing components and prevents non-Microsoft extensions from running.\r\n\u2022\t\r\n\r\nMultimedia content is disabled. This setting prevents music, animations, and video clips from running.\r\n\r\nFor more information regarding Internet Explorer Enhanced Security Configuration, see the guide, Managing Internet Explorer Enhanced Security Configuration, at the following Web site.\r\n\r\nWhat does the update do?\r\nThe update removes the vulnerability by modifying the way that the affected operating system checks message inputs under certain circumstances.\r\n\r\nWhen this security bulletin was issued, had this vulnerability been publicly disclosed?\r\nNo. Microsoft received information about this vulnerability through responsible disclosure.\r\nTop of sectionTop of section\r\nTop of sectionTop of section\r\n\t\r\nEMF Elevation of Privilege Vulnerability CVE-2007-1212:\r\n\r\nAn elevation of privilege vulnerability exists in the rendering of Enhanced Metafile (EMF) image format files.
