MariaDB Server 5.5.x < 5.5.49 Multiple DoS

high Nessus Network Monitor Plugin ID 9451

Synopsis

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

Description

MariaDB is a community-developed fork of the MySQL relational database. The version of MariaDB installed on the remote host is 5.5.x earlier than 5.5.49, and is therefore affected by multiple vulnerabilities :

- A flaw exists in the 'my_decimal_precision_to_length_no_truncation()' function in 'item_cmpfunc.cc' that is triggered when handling SELECT CASE statements. This may allow an authenticated attacker to crash the database.
- An overflow condition exists in the 'audit_plugin_so_init()' function in 'plugin/server_audit/server_audit.c'. The issue is triggered as user-supplied input is not properly validated. This may allow an authenticated attacker to cause a buffer overflow, resulting in an unspecified impact that may include a denial of service or potentially allowing the execution of arbitrary code.

Solution

Upgrade to version 5.5.49 or later.
