    Synopsis
    ========

    A vulnerability has been found in GNOME Autoar that could allow a
    remote attacker to execute arbitrary code.

    Background
    ==========

    GNOME Autoar provides functions and widgets for GNOME applications
    which want to use archives as a method to transfer directories over the internet.

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

    -------------------------------------------------------------------
    Package / Vulnerable / Unaffected
    -------------------------------------------------------------------
    1 app-arch/gnome-autoar < 0.3.1 >= 0.3.1

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

    It was discovered that GNOME Autoar could extract files outside of the
    intended directory.

    Impact
    ======

    A remote attacker could entice a user to open a specially crafted
    archive using GNOME Autoar, possibly resulting in execution of
    arbitrary code with the privileges of the process or a Denial of
    Service condition.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All GNOME Autoar users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-arch/gnome-autoar-0.3.1"
