An elevation of privilege vulnerability exists in the Local Security Authority Subsystem Service (LSASS) when an authenticated attacker sends a specially crafted authentication request. A remote attacker who successfully exploited this vulnerability could cause an elevation of privilege on the target system’s LSASS service.
The security update addresses the vulnerability by changing the way that LSASS handles specially crafted authentication requests.
