New! Plugin Severity Now Using CVSS v3

The remote Windows host is affected multiple vulnerabilities.


The remote Windows host is missing a security update. It is, therefore, affected by a denial of service vulnerability in the Local Security Authority Subsystem Service (LSASS) component due to improper handling of authentication requests. An unauthenticated, remote attacker can exploit this to trigger a reboot of the system.


Microsoft has released a set of patches for Windows Vista, 2008, 7, and 2008 R2.
