MariaDB Server 5.5.x < 5.5.52 Multiple DoS

Medium

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 5.5.52, and is therefore affected by multiple vulnerabilities :

- A flaw exists in the 'Item_field::fix_after_pullout()' function in 'sql/item.cc' that is triggered when handling a prepared statement with conversion to semi-join. This may allow an attacker to cause a crash. (OSVDB 144428) - A flaw exists in the 'mysql_admin_table()' function in 'sql/sql_admin.cc' that is triggered when handling reexecution of certain 'ANALYZE TABLE' prepared statements. This may allow an attacker to cause a crash. (OSVDB 144429)

Solution

Upgrade to version 5.5.52 or later.
