      DivX Player Skin Directory Traversal
    ------------------------------------------------------------------------

    SUMMARY

    As the name suggests, <http://www.divx.com/divx/player/> DivX Player is
    "a Windows player for DivX files. It is included by default in the DivX
    codec distributed by DivXNetworks".

    Due to improper filtering by the DivX Player skin installer, an attacker
    can cause DivX Player to overwrite arbitrary files by utilizing a
    directory traversal vulnerability.

    DETAILS

    Vulnerable Systems:
     * DivX Player version 2.6 and prior

    The skins used by DivX Player are actually zip files containing all the
    needed images and a script file. When the player loads a skin, it unpacks
    the skin in the temporary system directory into a folder folder named with
    the DPS's name.

    An attacker can overwrite the files on the victim's disk in that is
    located the temporary folder (usually c:) using the classical directory
    traversal path like:
      ..\..\..\..\windows\notepad.exe

    Can be used both slash and backslash.
