"The version of MariaDB running on the remote host is 10.1.x prior to
10.1.20. It is, therefore, affected by multiple denial of service
vulnerabilities :

  - A denial of service vulnerability exists in the
    trx_state_eq() function due to improper handling of
    state errors. An authenticated, remote attacker can
    exploit this to crash the database.

  - A denial of service vulnerability exists in the
    check_duplicate_key() function due to improper handling
    of error messages. An authenticated, remote attacker can
    exploit this to crash the database.

  - A denial of service vulnerability exists in the
    lock_rec_queue_validate() function in lock/lock0lock.cc
    due to improper handling of lock requests. An
    authenticated, remote attacker can exploit this to crash
    the database.

  - A denial of service vulnerability exists in the
    destroy() function in sql/sql_select.cc due to improper
    handling of a specially crafted query. An authenticated,
    remote attacker can exploit this to crash the database.

  - A denial of service vulnerability exists in the
    calculate_cond_selectivity_for_table() function in
    sql/opt_range.cc due to improper handling of
    'thd->no_errors'. An authenticated, remote attacker can
    exploit this to crash the database.

  - A denial of service vulnerability exists in the
    date_add_interval() function in sql/sql_time.cc due to
    improper handling of INTERVAL arguments. An
    authenticated, remote attacker can exploit this to crash
    the database.

  - A denial of service vulnerability exists in
    sql/item_subselect.cc due to improper handling of
    queries from the select/unit tree. An authenticated,
    remote attacker can exploit this to crash the database.

  - A denial of service vulnerability exists in the
    check_well_formed_result() function in sql/item.cc due
    to improper handling of row validation. An
    authenticated, remote attacker can exploit this to crash
    the database.

  - A denial of service vulnerability exists in
    sql/statistics.cc due o improper handling of stat
    tables. An authenticated, remote attacker can exploit
    this to crash the database.

  - A denial of service vulnerability exists in the
    parse_filter_rule() function in sql/rpl_filter.cc 
    that is triggered during the clearing of wildcards. An
    authenticated, remote attacker can exploit this to crash
    the database.

  - A denial of service vulnerability exists in the
    lock_reset_lock_and_trx_wait() function in
    storage/innobase/lock/lock0lock.cc due to improper
    handling of NULL values in wait_lock. An authenticated,
    remote attacker can exploit this to crash the database.

  - A denial of service vulnerability exists in the
    safe_charset_converter() function in sql/item.cc due to
    improper handling of a specially crafted subselect query
    item. An authenticated, remote attacker can exploit this
    to crash the database.");
