    Synopsis
    ========

    Multiple overflows have been found in the imlib library image decoding
    routines, potentially allowing execution of arbitrary code.

    Background
    ==========

    imlib is an advanced replacement library for image manipulation
    libraries like libXpm. It is called by numerous programs, including
    gkrellm and several window managers, to help in displaying images.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 media-libs/imlib <= 1.9.14-r2 >= 1.9.14-r3

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

    Pavel Kankovsky discovered that several overflows found in the libXpm
    library (see GLSA 200409-34) also applied to imlib. He also fixed a
    number of other potential flaws.

    Impact
    ======

    A remote attacker could entice a user to view a carefully-crafted 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 imlib library.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All imlib users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=media-libs/imlib-1.9.14-r3"
