MariaDB 10.11.18 is a Stable (GA) corrective release of MariaDB Community Server 10.11.

For an overview of MariaDB 10.11 see the MariaDB 10.11 Changes & Improvements page.

Notable Items

MariaDB Cluster (Galera)

• A parameter-injection gap existed in wsrep_sst_rsync because it failed to validate the joiner-supplied WSREP_SST_OPT_REMOTE_USER and WSREP_SST_OPT_REMOTE_PSWD values before interpolating them into the donor-written stunnel.conf and the rsync magic file MDEV-39648

• An appropriately privileged user (with SUPER privileges) could execute shell commands as the uid of the mariadbd process because the values of the system variables wsrep_sst_donor and wsrep_sst_receive_address, which can be modified at runtime, were not properly sanitized when used to construct a shell command MDEV-39676

• The wsrep_notify_cmd functionality was susceptible to a parameter-injection vulnerability, as it failed to validate the peer-supplied wsrep_node_name and wsrep_node_incoming_address values before interpolating them into the notification command line MDEV-39721

• In a multi-table UPDATE, the table list could incorrectly include tables that were not opened because they were not truly modified. This occurred when an UPDATE modified a table referenced by a foreign key constraint from a table that was not part of the multi-table update MDEV-3968

• Galera updated to 26.4.27

Server

• The server failed to parse schema-qualified table names when the unquoted table name began with a digit MDEV-39654

General

• As per the MariaDB Deprecation Policy, this will be the last release of MariaDB 10.11 for OpenSUSE Leap 15.6 and Fedora 42
