    Synopsis
    ========

    Ark was found to allow arbitrary file overwrite, possibly allowing
    arbitrary code execution.

    Background
    ==========

    Ark is a graphical file compression/decompression utility with support
    for multiple formats.

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

    -------------------------------------------------------------------
    Package / Vulnerable / Unaffected
    -------------------------------------------------------------------
    1 kde-apps/ark < 20.04.3-r1 >= 20.04.3-r1

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

    A maliciously crafted archive with "../" in the file path(s) could
    install files anywhere in the user's home directory upon extraction.

    Impact
    ======

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

    Workaround
    ==========

    Avoid opening untrusted archives.

    Resolution
    ==========

    All Ark users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=kde-apps/ark-20.04.3-r1"

    References
    ==========
