Microsoft Security Bulletin MS08-068
Vulnerability in SMB Could Allow Remote Code Execution (957097)
Severity: ImportantVulnerabilities:
- SMB Credential Reflection Vulnerability - CVE-2008-4037
A remote code execution vulnerability exists in the way that Microsoft Server Message Block (SMB) Protocol handles NTLM credentials when a user connects to an attacker's SMB server. This vulnerability allows an attacker to replay the user's credentials back to them and execute code in the context of the logged-on user. If a user is logged on with administrative user rights, 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. 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.
Microsoft Security Bulletin MS08-069
Vulnerabilities in Microsoft XML Core Services Could Allow Remote Code Execution (955218)
Severity: CriticalVulnerabilities:
- MSXML Nested Tag Vulnerability - CVE-2007-0099
A remote code execution vulnerability exists in the way that Microsoft XML Core Services handles nested tags. The vulnerability could allow remote code execution if a user browses a Web site that contains specially crafted content or opens specially crafted HTML e-mail. 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. 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. - MSXML DTD Cross-Domain Scripting Vulnerability - CVE-2008-4029
An information disclosure vulnerability exists in the way that Microsoft XML Core Services handles error checks for external document type definitions (DTDs). The vulnerability could allow information disclosure if a user browses a Web site that contains specially crafted content or opens specially crafted HTML e-mail. An attacker who successfully exploited this vulnerability could read data from a Web page in another domain in Internet Explorer. In all cases, however, an attacker would have no way to force users to visit these Web sites. - MSXML Chunked Request Vulnerability - CVE-2008-4033
An information disclosure vulnerability exists in the way that Microsoft XML Core Services handles transfer-encoding headers. The vulnerability could allow information disclosure if a user browses a Web site that contains specially crafted content or opens specially crafted HTML e-mail. An attacker who successfully exploited this vulnerability could read data from a Web page in another domain in Internet Explorer. In all cases, however, an attacker would have no way to force users to visit these Web sites.
