1. Overview:

Microsoft issued a security bulletin which contained security advisory MS10-068. This security update resolves a vulnerability in Active Directory, Active Directory Application Mode (ADAM), and Active Directory Lightweight Directory Service (AD LDS). The vulnerability could allow elevation of privilege if an authenticated attacker sent specially crafted Lightweight Directory Access Protocol (LDAP) messages to a listening LSASS server. In order to successfully exploit this vulnerability, an attacker must have a member account within the target Windows domain. However, the attacker does not need to have a workstation joined to the Windows domain. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-0820 to this issue. A description of the vulnerability may be found at:
