Description:
A vulnerability was reported in Adobe Reader and Acrobat. A remote user can modify a portion of a file execution warning dialog.
A remote user can create a specially crafted PDF file containing an embedded executable to be automatically executed via the '/launch' command. When the target user loads the PDF file, a dialog box will be displayed to ask the target user to authorize the launching of the executable. The remote user can name the embedded executable so that arbitrary text will be displayed in the 'file name' portion of the dialog box, which may confuse some target users and convince them to authorize the launching of the executable.
Didier Stevens reported this vulnerability.

[Editor's note: The '/launch' command and the capability to embed executables is part of the PDF specification and is not a vulnerability in the specific Adobe implementation. However, the potentially confusing manner in which the embedded executable warning dialog is displayed is a vulnerability in the Adobe product.]
