"The version of MariaDB running on the remote host is 10.2.x prior to
10.2.3. 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
    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
    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 the
    check_contains() function in sql/item_jsonfunc.cc due to
    improper handling of a specially crafted array. An
    authenticated, remote attacker can exploit this to crash
    the database.

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

  - A denial of service vulnerability exists in the
    val_str() function in sql/item_jsonfunc.cc due to
    improper handling of scalar values. An authenticated,
    remote attacker can exploit this to crash the database.

  - A denial of service vulnerability exists in the
    mark_object() and mark_array() functions in
    strings/json_lib.c due to improper handling of
    JSON_VALID selections. An authenticated, remote attacker
    can exploit this to crash the database.

  - A denial of service vulnerability exists in the
    mark_object() and mark_array() functions in
    strings/json_lib.c due to improper handling of
    JSON arrays. An authenticated, remote attacker can
    exploit this to crash the database.

  - A denial of service vulnerability exists in the
    mark_object() and mark_array() functions in
    strings/json_lib.c due to improper handling of
    JSON_VALID selections. An authenticated, remote attacker
    can exploit this to crash the database.

  - A denial of service vulnerability exists in the
    fix_length_and_dec() function in sql/item_jsonfunc.cc
    due to improper handling of JSON casting. An
    authenticated, remote attacker can exploit this to crash
    the database.

  - A denial of service vulnerability exists in the
    fparse_one_or_all() function in sql/item_jsonfunc.cc due
    to improper handling of input passed via the
    'one_or_all' parameter. An authenticated, remote
    attacker can exploit this to crash the database.

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

  - A denial of service vulnerability exists in the
    val_int() function in sql/item_jsonfunc.cc due to
    improper handling of NULL paths. An authenticated,
    remote attacker can exploit this to crash the database.

  - A denial of service vulnerability exists in the
    merge_buffers() function in sql/filesort.cc due to
    improper handling of sort_union optimization. An
    authenticated, remote attacker can exploit this to crash
    the database.

  - A denial of service vulnerability exists in the
    mysql_rm_table_no_locks() function in sql/sql_table.cc
    that is triggered when dropping temporary tables. An
    authenticated, remote attacker can exploit this to crash
    the database.

  - A denial of service vulnerability exists in the
    check_view_single_update() function in sql/sql_insert.cc
    that is triggered when inserting specially crafted
    tables. 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.");
