Discussion

Microsoft Windows LSASS Buffer Overrun Vulnerability

Microsoft Windows LSASS (Local Security Authority Subsystem Service) is prone to a remotely exploitable buffer overrun vulnerability. The specific vulnerable system component is LSASRV.DLL. Successful exploitation of this issue could allow a remote attacker to execute malicious code on a vulnerable system, resulting in full system compromise.

This issue could be exploited by an anonymous user on Microsoft Windows 2000 and XP operating systems. The issue may reportedly only be exploited by local, authenticated users on Microsoft Windows Server 2003 and Microsoft Windows XP 64-Bit Edition 2003. Microsoft has stated that a local administrator could exploit the issue on these platforms, though this does not appear to pose any additional security risk as the administrator will likely already have complete control over the system.
