    "MPlayer is a movie player for LINUX (runs on many other Unices, and
    non-x86 CPUs, see the documentation). It plays most MPEG, VOB, AVI,
    OGG/OGM, VIVO, ASF/WMA/WMV, QT/MOV/MP4, FLI, RM, NuppelVideo, YUV4MPEG,
    FILM, RoQ, PVA files, supported by many native, XAnim, and Win32 DLL
    codecs. You can watch VideoCD, SVCD, DVD, 3ivx, DivX 3/4/5 and even WMV
    movies, too."

    A vulnerability exists in the MPlayer HTTP parser which may allow an
    attacker to craft a special HTTP header ("Location:") which will trick
    MPlayer into executing arbitrary code on the user's computer.
    </p>

    An attacker without privileges may exploit this vulnerability remotely,
