Real Networks RealONE Player vulnerable to arbitrary command execution via crafted html in the skin file

Overview

RealNetwork's RealJukebox and RealONE Gold players are media applications that permit users to stream audio and video from local and internet sources. A vulnerability exists in the applications that could permit the execution of arbitrary commands by a remote attacker.

I. 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. Examples of documents that could have skin files embedded are HTML formatted web pages, and email messages.

According to the advisory released by RealNetworks, the following versions are vulnerable:

    RealOne Player Gold US for Windows

    RealJukebox2 version 379 Japanese and version 340 US for Microsoft Windows

    RealJukebox 2 Plus version 379 Japanese and version 340 US for Microsoft Windows

    II. Impact

    A remote attacker can execute arbitrary script on the system in the "My Computer" Security Zone of Internet Explorer, which can lead to the execution of arbitrary commands with the privileges of the current user.

    III. Solution

    RealNetworks has released a security advisory with patches to address this issue.
