  • Cross-Domain Information Disclosure Vulnerability - CVE-2008-3474
    An information disclosure vulnerability exists in Internet Explorer where script can gain access to another browser window in another domain or Internet Explorer zone. An attacker could exploit the vulnerability by constructing a specially crafted Web page that could allow information disclosure if a user viewed the Web page.
  • Uninitialized Memory Corruption Vulnerability - CVE-2008-3475
    A remote code execution vulnerability exists in the way Internet Explorer accesses an object that has not been correctly initialized or that has been deleted. An attacker could exploit the vulnerability by constructing a specially crafted Web page. When a user views the Web page, the vulnerability could allow remote code execution. An attacker who successfully exploited this vulnerability could gain the same user rights as the logged-on user.
  • HTML Objects Memory Corruption Vulnerability - CVE-2008-3476
    A remote code execution vulnerability exists in Internet Explorer due to attempts to access uninitialized memory in certain situations. An attacker could exploit the vulnerability by constructing a specially crafted Web page. When a user views the Web page, the vulnerability could allow remote code execution. An attacker who successfully exploited this vulnerability could gain the same user rights as the logged-on user.

Microsoft Security Bulletin MS08-059

Vulnerability in Host Integration Server RPC Service Could Allow Remote Code Execution (956695)

Severity: Critical
Vulnerabilities:
  • HIS RPC Buffer Overflow Vulnerability - CVE- 2008-3466
    A remote code execution vulnerability exists in the SNA Remote Procedure Call (RPC) service for Host Integration Server. An attacker could exploit the vulnerability by constructing a specially crafted RPC request. The vulnerability could allow remote code execution. An attacker who successfully exploited this vulnerability could take complete control of an affected system.

Microsoft Security Bulletin MS08-060

Vulnerability in Active Directory Could Allow Remote Code Execution(957280)

Severity: Critical
Vulnerabilities:
  • Active Directory Overflow Vulnerability - CVE-2008-4023
    A remote code execution vulnerability exists in implementations of Active Directory on Microsoft Windows 2000 Server. The vulnerability is due to incorrect memory allocation when receiving specially crafted LDAP requests. An attacker who successfully exploited this vulnerability could take complete control of an affected system.

Microsoft Security Bulletin MS08-061

Vulnerabilities in Windows Kernel Could Allow Elevation of Privilege(954211)

Severity: Important
Vulnerabilities:
  • Windows Kernel Window Creation Vulnerability - CVE-2008-2250
    An elevation of privilege vulnerability exists because the Windows kernel does not properly validate properties of a window passed during the new window creation process. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
  • Windows Kernel Memory Corruption Vulnerability - CVE-2008-2252
    An elevation of privilege vulnerability exists due to the Windows kernel improperly validating input passed from user mode to the kernel. The vulnerability could allow an attacker to run code with elevated privileges. An attacker who successfully exploited this vulnerability could execute arbitrary code and 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.

Microsoft Security Bulletin MS08-062

Vulnerability in Windows Internet Printing Service Could Allow Remote Code Execution(953155)

Severity: Important
Vulnerabilities:
  • Vulnerability in Windows Internet Printing Service Could Allow Remote Code Execution(953155)
