Apple Mac OS X Login Window Local DoS
Physical Access Required Denial of Service
Loss of Availability
Exploit Public

- 漏洞描述

Mac OS X contains a flaw that may allow a local denial of service. The issue is triggered when the 'loginwindow' application has been configured to display the login window as 'Name and password' and the 'Show the Restart, Sleep, and Shut Down buttons' option is disabled. By providing '>restart', '>power' or '>shutdown' in the username field of the login window, a malicious user can force a reboot or shutdown of the machine without providing a password first resulting in a loss of availability.
