    Synopsis
    ========

    A vulnerability has been discovered in MariaDB which could result in
    the arbitrary execution of code.

    Background
    ==========

    MariaDB is an enhanced, drop-in replacement for MySQL.

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

    -------------------------------------------------------------------
    Package / Vulnerable / Unaffected
    -------------------------------------------------------------------
    1 dev-db/mariadb < 10.5.6 >= 10.5.6:10.5
    >= 10.4.13-r3:10.4
    >= 10.3.23-r3:10.3
    >= 10.2.22-r3:10.2

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

    It was discovered that MariaDB did not properly validate the content of
    a packet received from a server.

    Impact
    ======

    A remote attacker could send a specially crafted packet to WSREP
    service, 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 MariaDB 10.5.x users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-db/mariadb-10.5.6:10.5"

    All MariaDB 10.4.x users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-db/mariadb-10.4.13-r3:10.4"

    All MariaDB 10.3.x users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-db/mariadb-10.3.23-r3:10.3"

    All MariaDB 10.2.x users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-db/mariadb-10.2.22-r3:10.2"
