      REAL One Player Code Execution Through Malformed Media File
    ------------------------------------------------------------------------

    SUMMARY

    RealOne and RealPlayer are "the most widely used products for internet
    media delivery. There are currently in excess of 200 million users that
    use these products worldwide". By crafting a malformed .RA, .RM, .RV or
    RMJ file it possible to cause heap corruption that can lead to execution
    of arbitrary code.

    DETAILS

    Vulnerable Systems:
     * RealOne Player (English)
     * RealOne Player v2 (all languages),
     * RealPlayer 10 (English, German and Japanese)
     * RealPlayer 8 (all languages)
     * RealPlayer Enterprise (all versions, standalone and "as configured" by
    the RealPlayer Enterprise Manager)

    By forcing a browser or enticing a user to a website containing such a
    file, arbitrary attacker supplied code could be executed on the target
    machine. This code will run in the security context of the logged on user.
    Another attacker vector is via an e-mail attachment. NGSResearchers have
    created reliable exploits to take advantage of these issues. Due to the
    ease of exploitation these vulnerabilities should be considered as high
    risk and customers are urged to update their players as soon as is
    possible.

    Fix Information:
    For the various fix options available for different types of REAL
    products, NGS suggest visiting
