[原文]Unknown vulnerability in Mac OS X before 10.3 allows local users to access Dock functions from behind Screen Effects when Full Keyboard Access is enabled using the Keyboard pane in System Preferences.
Mac OS X contains a flaw that may allow a malicious user to bypass screen locking. The issue is triggered when the screen effect is active, and keys pressed before the authentication window appears will be sent to the general user environment. It is possible that the flaw may allow a malicious user to launch applications in spite of screen locking resulting in a loss of integrity.
Currently, there are no known workarounds or upgrades to correct this issue. However, Apple has released a patch to address this vulnerability.
