Microsoft » Windows Xp : Security Vulnerabilities, CVEs, (Gain Privilege) CVSS score >= 9

The LDAP over SSL (aka LDAPS) implementation in Active Directory, Active Directory Application Mode (ADAM), and Active Directory Lightweight Directory Service (AD LDS) in Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2, R2, and R2 SP1, and Windows 7 Gold and SP1 does not examine Certificate Revocation Lists (CRLs), which allows remote authenticated users to bypass intended certificate restrictions and access Active Directory resources by leveraging a revoked X.509 certificate for a domain account, aka "LDAPS Authentication Bypass Vulnerability."

Microsoft Windows XP Professional SP2, Vista, and Server 2003 and 2008 does not properly assign activities to the (1) NetworkService and (2) LocalService accounts, which might allow context-dependent attackers to gain privileges by using one service process to capture a resource from a second service process that has a LocalSystem privilege-escalation ability, related to improper management of the SeImpersonatePrivilege user right, as originally reported for Internet Information Services (IIS), aka Token Kidnapping.

The Server Message Block (SMB) driver (MRXSMB.SYS) in Microsoft Windows 2000 SP4, XP SP1 and SP2, and Server 2003 SP1 and earlier allows local users to execute arbitrary code by calling the MrxSmbCscIoctlOpenForCopyChunk function with the METHOD_NEITHER method flag and an arbitrary address, possibly for kernel memory, aka the "SMB Driver Elevation of Privilege Vulnerability."
