MS10-068 Vulnerability in Local Security Authority Subsystem Service Could Allow Elevation of Privilege (983539) Windows 7 Critical 15-09-2010

Technical Information

Brief overview of the risk:
This security update resolves a privately reported 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.
Detailed Information on the risk:

An authenticated elevation of privilege vulnerability exists in Microsoft Windows due to the way that the Local Security Authority Subsystem Service (LSASS) improperly handles certain Lightweight Directory Access Protocol (LDAP) messages. The vulnerability exists in implementations of Active Directory, Active Directory Application Mode (ADAM), and Active Directory Lightweight Directory Service (AD LDS). An attacker must have previously authenticated with the LSASS server prior to exploiting this issue. 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.
