Description: A vulnerability was reported in Adobe Flash Player. A remote user can hijack the target user's click actions.
A remote user can create specially crafted Flash content that, when loaded by the target user, will hijack the target user's click
actions. This can be exploited to cause links to load that are different links than those displayed to the target user. For example,
this can be exploited to access the target user's camera and microphone without the target user's knowledge.
