| Description: | MySQL is a multi-user, multi-threaded SQL database server. It consists of the MySQL server daemon (mysqld) and many client programs and libraries.
This update fixes several vulnerabilities in the MySQL database server. Information about these flaws can be found on the Oracle Critical Patch Update Advisory page, listed in the References section. (CVE-2014-0386, CVE-2014-0393, CVE-2014-0401, CVE-2014-0402, CVE-2014-0412, CVE-2014-0437, CVE-2013-5908)
A buffer overflow flaw was found in the way the MySQL command line client tool (mysql) processed excessively long version strings. If a user connected to a malicious MySQL server via the mysql client, the server could use this flaw to crash the mysql client or, potentially, execute arbitrary code as the user running the mysql client. (CVE-2014-0001)
The CVE-2014-0001 issue was discovered by Garth Mollett of the Red Hat Security Response Team.
This update also fixes the following bug:
Prior to this update, MySQL did not check whether a MySQL socket was actually being used by any process before starting the mysqld service. If a particular mysqld service did not exit cleanly while a socket was being used by a process, this socket was considered to be still in use during the next start-up of this service, which resulted in a failure to start the service up. With this update, if a socket exists but is not used by any process, it is ignored during the mysqld service start-up. (BZ#1058719)
These updated packages upgrade MySQL to version 5.1.73. Refer to the MySQL Release Notes listed in the References section for a complete list of changes.
All MySQL users should upgrade to these updated packages, which correct these issues. After installing this update, the MySQL server daemon (mysqld) will be restarted automatically.
