Description

RealJukebox and RealONE Gold contain a vulnerability that allows files to be stored in a predictable temporary file path location during the processing of a skin file. Skins permit users to customize the appearance of the player. This vulnerability can be triggered by the opening of a skin file, or any document that has a skin file embedded in it.
