(tiff: Buffer overflows in image decoding)

    Chris Evans found heap-based overflows in RLE decoding routines in
    tif_next.c, tif_thunder.c and potentially tif_luv.c.
  
Impact :

    A remote attacker could entice a user to view a carefully crafted TIFF
    image file, which would potentially lead to execution of arbitrary code
    with the rights of the user viewing the image. This affects any program
    that makes use of the tiff library, including GNOME and KDE web browsers or
    mail readers.
  
Workaround :

    There is no known workaround at this time."

    xv makes use of the tiff library and needs to be recompiled to receive the
    new patched version of the library. All xv users should also upgrade to the
    latest version:
    # emerge sync
