Home Microsoft Security Bulletin (MS06-004, MS06-005, MS06-006, MS06-007, MS06-008, MS06-009, MS06-010)Update to Advisory AV06-006 http://www.microsoft.com/technet/security/Bulletin/MS06-005.mspx Number: AV06-006 PURPOSEThe purpose of this advisory is to bring attention to the following vulnerabilities (2 Critical, 5 Important) in some Microsoft products. MS06-004: Cumulative Security Update for Internet Explorer (910620) ASSESSMENT:A remote code execution vulnerability exists in Internet Explorer due to the way it handles Windows Metafile (WMF) images. An attacker could exploit the vulnerability by constructing a specially crafted WMF image that could potentially allow remote code execution if a user visited a malicious web site, opened or previewed an e-mail message, or opened a specially crafted attachment in e-mail. An attacker who successfully exploited this vulnerability could take complete control of an affected system. Impact of Vulnerability: Remote Code Execution Microsoft's Maximum Severity Rating: Critical Affected Software: Affected Components: SUGGESTED ACTIONPSEPC recommends that administrators test and install the update at the earliest opportunity. MS06-005: Vulnerability in Windows Media Player Could Allow Remote Code Execution (911565) ASSESSMENT:A remote code execution vulnerability exists in Windows Media Player due to the way it handles the processing of bitmap files. An attacker could exploit the vulnerability by constructing a malicious bitmap file (.bmp) that could potentially allow remote code execution if a user visited a malicious web site or viewed a malicious e-mail message. An attacker who successfully exploited this vulnerability could take complete control of an affected system. However, significant user interaction is required to exploit this vulnerability. Impact of Vulnerability: Remote Code Execution Microsoft's Maximum Severity Rating: Critical Affected Software: Affected Components: SUGGESTED ACTIONPSEPC recommends that administrators test and install the update at the earliest opportunity. MS06-006: Vulnerability in Windows Media Player Plug-in with Non-Microsoft Internet Browsers Could Allow Remote Code Execution (911564) ASSESSMENT:A remote code execution vulnerability exists in the Windows Media Player plug-in for non-Microsoft Internet browsers due to the way the Windows Media Player plug-in handles a malformed EMBED element. An attacker could exploit the vulnerability by constructing a malicious EMBED element that could potentially allow remote code execution if a user visited a malicious web site. An attacker who successfully exploited this vulnerability could take complete control of an affected system. Impact of Vulnerability: Remote Code Execution Microsoft's Maximum Severity Rating: Important Affected Software: SUGGESTED ACTIONPSEPC recommends that administrators test and install the update at the earliest opportunity. MS06-007: Vulnerability in TCP/IP Could Allow Denial of Service (913446) ASSESSMENT:A specially crafted IGMP packet could cause the affected system to stop responding. Impact of Vulnerability: Denial of Service Microsoft's Maximum Severity Rating: Important Affected Software: SUGGESTED ACTIONPSEPC recommends that administrators test and install the update at the earliest opportunity. MS06-008: Vulnerability in Web Client Service Could Allow Remote Code Execution (911927) ASSESSMENT:A remote code execution vulnerability exists in the way that Windows processes Web Client requests that could allow an attacker who successfully exploited this vulnerable to take complete control of the affected system. Impact of Vulnerability: Remote Code Execution Microsoft's Maximum Severity Rating: Important Affected Software: SUGGESTED ACTIONPSEPC recommends that administrators test and install the update at the earliest opportunity. MS06-009: Vulnerability in the Korean Input Method Editor Could Allow Elevation of Privilege (901190) ASSESSMENT:A privilege elevation vulnerability exists in the Windows and Office Korean Input Method Editor (IME). This vulnerability could allow a malicious user to take complete control of an affected system. For an attack to be successful an attacker must be able to interactively logon to the affected system. Impact of Vulnerability: Elevation of Privilege Microsoft's Maximum Severity Rating: Important Affected Software: SUGGESTED ACTIONPSEPC recommends that administrators test and install the update at the earliest opportunity. MS06-010: Vulnerability in PowerPoint 2000 Could Allow Information Disclosure (889167) ASSESSMENT:An Information Disclosure vulnerability exists in PowerPoint. An attacker who successfully exploited this vulnerability could remotely attempt to access objects in the Temporary Internet Files Folder (TIFF) explicitly by name. Note that this vulnerability would not allow an attacker to execute code or to elevate their user rights directly, but it could be used to produce useful information that could be used to try to further compromise the affected system. Impact of Vulnerability: Information Disclosure Microsoft's Maximum Severity Rating: Important Affected Software: SUGGESTED ACTIONPSEPC recommends that administrators test and install the update at the earliest opportunity. Note to ReadersCanadian Cyber Incident Response Centre (CCIRC) collects information related to cyber threats to, and incidents involving, Canadian critical infrastructure. This allows us to monitor and analyze threats and to issue alerts, advisories and other information products. To report threats or incidents, please contact the Government Operations Centre (GOC) at (613) 991-7000 or goc-cog@psepc-sppcc.gc.ca by e-mail. Unauthorized use of computer systems and mischief in relation to data are serious Criminal Code offences in Canada. Any suspected criminal activity should be reported to local law enforcement organizations. The Royal Canadian Mounted Police (RCMP) National Operations Centre (N.O.C.) provides a 24/7 service to receive such reports or to redirect callers to local law enforcement organizations. The N.O.C. can be reached at (613) 993-4460. National security concerns should be reported to the Canadian Security Intelligence Service (CSIS) at (613) 993-9620. For urgent matters or to report any incidents, please contact the Government Operations Centre at: Phone: (613) 991-7000 For general information on critical infrastructure protection and emergency preparedness, please contact PSEPC's Public Affairs division at: Telephone: (613) 944-4875 or 1-800-830-3118
