A vulnerability has been reported in Mac OS X, which can be exploited by malicious users to perform actions while Screen Lock is enabled.

The vulnerability is caused due to a race condition when the Screen Lock is enabled. The problem is that it is still possible to perform actions in a limited period of time until the authentication window is displayed. This can potentially be exploited to manipulate the user environment (eg. start applications, close open applications, perform shortcut operations etc.).

The vulnerability has been reported in version 10.3 Build 7B85. Other versions may also be affected.

Solution
Update to version 10.3.2 or later.
