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 5.5.47 or 10.0.x earlier than 10.0.23, and is therefore affected by multiple DoS vulnerabilities :
- A flaw exists in the 'i_s_innodb_buffer_pool_pages_blob_fill()' function in 'storage/xtradb/handler/i_s.cc' that is triggered during the handling of buffer pages. This may allow an authenticated attacker to crash the database.
- A flaw exists in the 'mysql_prepare_create_table()' function in 'sql_table.cc'. The issue is triggered during the handling of a comma buffer that is greater than 0. This may allow an authenticated attacker to cause a denial of service.
Solution
Upgrade to version 10.0.23 or later. If version 10.0.x cannot be obtained, version 5.5.47 has also been patched for these issues.
