Fedora Update Notification
FEDORA-2018-e31f52c5ee
2018-05-15 19:52:12.739386
——————————————————————————–

Name : mysql-mmm
Product : Fedora 27
Version : 2.2.1
Release : 20.fc27
URL : http://mysql-mmm.org
Summary : Multi-Master Replication Manager for MySQL
Description :
MMM (MySQL Master-Master Replication Manager) is a set of flexible scripts
to perform monitoring/failover and management of MySQL Master-Master
replication configurations (with only one node writable at any time). The
toolset also has the ability to read balance standard master/slave
configurations with any number of slaves, so you can use it to move virtual
IP addresses around a group of servers depending on whether they are behind
in replication. In addition to that, it also has scripts for data backups,
resynchronization between nodes etc.

Update Information:

# Multi-Master Replication Manager for MySQL mmm_agentd Remote Command Injection
Vulnerabilities This update adds data sanitization to inputs for the mmm agent.
Multiple exploitable remote command injection vulnerabilities exist in the MySQL
Master-Master Replication Manager (MMM) mmm_agentd daemon 2.2.1. mmm_agentd
commonly runs with root privileges and does not require authentication by
default. A specially crafted MMM protocol message can cause a shell command
injection resulting in arbitrary command execution with the privileges of the
mmm_agentd process. An attacker that can initiate a TCP session with mmm_agentd
can trigger these vulnerabilities. The impact of these vulnerabilities can be
lessened by configuring mmm_agentd to require TLS mutual authentication and by
using network ACLs to prevent hosts other than legitimate mmm_mond hosts from
accessing mmm_agentd. For example on Linux iptables rules can be used to block
access to the port mmm_agent is listening on from all hosts except the
mmm_monitor. The configuration of ssl can be used where firewall rules are not
practical. See Socket Documentation http://mysql-mmm.org/mysql-mmm.html#SEC58
Add to mmm_common.conf <socket> type ssl cert_file
/etc/ssl/certs/www.example.com.bundle.crt key_file
/etc/ssl/certs/www.example.com.key ca_file /etc/ssl/certs/ca-bundle.crt
# or ca-certificates.crt </socket> Now only those with access to the
private key can send commands. Whilst your web server certificate will do the
job, you may consider registering a dedicated certificate just for this task.
NOTE: By now there are a some good alternatives to MySQL-MMM. Maybe you
want to check out Galera Cluster which is part of MariaDB Galera Cluster
and Percona XtraDB Cluster. – http://mysql-mmm.org – http://galeracluster.com/
