Microsoft: Local Security Authority Subsystem Service Denial of Service Vulnerability
A denial of service vulnerability exists in the Windows Local Security Authority Subsystem Service (LSASS). A remote, but authenticated, attacker who successfully exploited this vulnerability could cause the target system to become nonresponsive. To exploit the vulnerability, a remote attacker would first have to log on to the system and send a specially crafted request to the target system. The security update addresses the vulnerability by changing the way that LSASS handles specially crafted requests.
