    Synopsis
    ========

    A vulnerability in Kleopatra allows arbitrary execution of code.

    Background
    ==========

    Kleopatra is a certificate manager and a universal crypto GUI. It
    supports managing X.509 and OpenPGP certificates in the GpgSM keybox
    and retrieving certificates from LDAP servers.

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

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

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

    Kleopatra did not safely escape command line parameters provided by
    URLs, which it configures itself to handle.

    Impact
    ======

    A remote attacker could entice a user to process a specially crafted
    URL via openpgp4fpr handler, possibly resulting in execution of
    arbitrary code with the privileges of the process, or cause a Denial of
    Service condition.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All Kleopatra users should upgrade to the latest version:

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