      RealPlayer vidplin.dll AVI Processing Heap Overflow
    ------------------------------------------------------------------------

    SUMMARY

     <http://www.real.com/player/?src=realplayer> RealPlayer is "a popular
    media player".

    A vulnerability in RealPlayer for Windows allows a remote attacker to
    reliably overwrite heap memory with arbitrary data and execute arbitrary
    code in the context of the user who executed the player.

    DETAILS

    Vulnerable Systems:
     * For Microsoft Windows:
      * RealPlayer 10.5 (6.0.12.1040-1069)
      * RealPlayer 10
      * RealOne Player v2
      * RealOne Player v1
      * RealPlayer 8
      * RealPlayer Enterprise

    The flaw exists within the vidplin.dll file used by RealPlayer. By
    specially crafting a malformed .avi movie file. When processing AVI files
    RealPlayer calls upon a specific DLL, vidplin.dll, where the vulnerability
    lies. Realplayer relies on a strf structure value and allocates a fixed
    memory space of 0x428 that can be overflowed with values greater than the
    fixed buffer size causing arbitrary code to be executed. This triggers a
    heap based overflow, and reliable code execution is then possible. This
    vulnerability can be trigger when a user views a webpage, or opens an .avi
    file via email, instant messenger, or other common file transfer programs.

    Vendor Status:
    RealNetworks has released a patch for this vulnerability. The patch can be
