MariaDB Server 10.2.x < 10.2.4 Multiple DoS

Medium Nessus Network Monitor Plugin ID 700000

Synopsis

The remote database server is affected by multiple Denial of Service (DoS) attack vectors.

Description

The version of MariaDB installed on the remote host is 10.2.x prior to 10.2.4, and is affected by multiple DoS vulnerabilities :

- A flaw exists in the 'Table_triggers_list::prepare_record_accessors()' function in 'sql/sql_trigger.cc' that is triggered during the handling of a specially crafted table. This may allow an authenticated attacker to crash the database.
- A flaw exists in the 'Item::decimal_precision()' function in 'sql/item.cc' that is triggered during the handling of a 'SELECT' statement in a crafted query. This may allow an authenticated attacker to crash the database.
- A flaw exists in the 'Field_time::store_TIME_with_warning()' function that is triggered when handling a specially crafted 'INSERT' query. This may allow an authenticated attacker to crash the database.
- A flaw exists in the 'SJ_TMP_TABLE::create_sj_weedout_tmp_table()' function in 'opt_subselect.cc' that is triggered when handling a specially crafted 'WHERE' query. This may allow an authenticated attacker to crash the database.

Solution

Upgrade to version 10.2.4 or later.
