    Synopsis
    ========

    Multiple heap-based overflows have been found in the tiff library image
    decoding routines, potentially allowing to execute arbitrary code with
    the rights of the user viewing a malicious image.

    Background
    ==========

    The tiff library contains encoding and decoding routines for the Tag
    Image File Format. It is called by numerous programs, including GNOME
    and KDE, to help in displaying TIFF images. xv is a multi-format image
    manipulation utility that is statically linked to the tiff library.

    Affected packages
    =================

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 media-libs/tiff < 3.6.1-r2 >= 3.6.1-r2
      2 media-gfx/xv <= 3.10a-r7 >= 3.10a-r8
        -------------------------------------------------------------------
         2 affected packages on all of their supported architectures.
        -------------------------------------------------------------------

    Description
    ===========

    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.

    Resolution
    ==========

    All tiff library users should upgrade to the latest version:

        # emerge sync

        # emerge -pv ">=media-libs/tiff-3.6.1-r2"
        # emerge ">=media-libs/tiff-3.6.1-r2"

    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

        # emerge -pv ">=media-gfx/xv-3.10a-r8"
        # emerge ">=media-gfx/xv-3.10a-r8"
