    Synopsis
    ========

    A vulnerability has been discovered in Thunar which may lead to
    arbitrary code execution

    Background
    ==========

    Thunar is a modern file manager for the Xfce Desktop Environment. Thunar
    has been designed from the ground up to be fast and easy to use. Its
    user interface is clean and intuitive and does not include any confusing
    or useless options by default. Thunar starts up quickly and navigating
    through files and folders is fast and responsive.

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

    Package Vulnerable Unaffected
    ---------------- ------------ ------------
    xfce-base/thunar < 4.17.3 >= 4.17.3

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

    A vulnerability has been discovered in Thunar. Please review the CVE
    identifier referenced below for details.

    Impact
    ======

    When called with a regular file as command line argument, Thunar
    would delegate to some other program without user confirmation
    based on the file type. This could be exploited to trigger code
    execution in a chain of vulnerabilities.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All Thunar users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=xfce-base/thunar-4.17.3"

    References
    ==========
