DESCRIPTION:
Krystian Kloskowski has discovered a vulnerability in Safari, which
can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to plug-ins being unloaded when
navigating to a new page while the user interacts with the plug-in
(e.g. displays the context menu). If the plug-in has called a
blocking function (e.g. TrackPopupMenu) before Safari navigates to
another page, the API call may block until after Safari unloaded the
plug-in, which can lead to the API call returning to freed memory.

The vulnerability is confirmed in version 5.1.2 (7534.52.7) on
Windows using the RealPlayer and Adobe Flash plug-ins. Other versions
may also be affected.

SOLUTION:
No effective workaround is currently available.
