MariaDB 5.5.x < 5.5.50 utf8mb4 Column Search DoS

critical Nessus Plugin ID 91767

Language:

Synopsis

The remote database server is affected by a denial of service vulnerability.

Description

The version of MariaDB running on the remote host is 5.5.x prior to 5.5.50. It is, therefore, affected by a flaw in the Item_func_match::fix_index() function within file sql/item_func.cc due to improper handling of a full-text search of the utf8mb4 column. An authenticated, remote attacker can exploit this to crash the server, resulting in a denial of service condition.

Solution

Upgrade to MariaDB version 5.5.50 or later.
