Security update for mariadb (moderate)

This update for mariadb to version 10.2.15 fixes the following issues:

These security issues were fixed:

• CVE-2018-2767: Enforse use of SSL/TLS in embedded server library (Return
  of BACKRONYM) (bsc#1088681).
• CVE-2018-2786: Vulnerability in the MySQL Server component of Oracle
  MySQL (subcomponent: InnoDB). Easily exploitable vulnerability allowed
  high privileged attacker with network access via multiple protocols to
  compromise MySQL Server. Successful attacks of this vulnerability can
  result in unauthorized ability to cause a hang or frequently repeatable
  crash (complete DOS) of MySQL Server as well as unauthorized update,
  insert or delete access to some of MySQL Server accessible data
  (bsc#1089987).
• CVE-2018-2759: Vulnerability in the MySQL Server component of Oracle
  MySQL (subcomponent: InnoDB). Easily exploitable vulnerability allowed
  high privileged attacker with network access via multiple protocols to
  compromise MySQL Server. Successful attacks of this vulnerability can
  result in unauthorized ability to cause a hang or frequently repeatable
  crash (complete DOS) of MySQL Server (bsc#1089987).
• CVE-2018-2777: Vulnerability in the MySQL Server component of Oracle
  MySQL (subcomponent: InnoDB). Easily exploitable vulnerability allowed
  high privileged attacker with network access via multiple protocols to
  compromise MySQL Server. Successful attacks of this vulnerability can
  result in unauthorized ability to cause a hang or frequently repeatable
  crash (complete DOS) of MySQL Server (bsc#1089987).
• CVE-2018-2810: Vulnerability in the MySQL Server component of Oracle
  MySQL (subcomponent: InnoDB). Easily exploitable vulnerability allowed
  high privileged attacker with network access via multiple protocols to
  compromise MySQL Server. Successful attacks of this vulnerability can
  result in unauthorized ability to cause a hang or frequently repeatable
  crash (complete DOS) of MySQL Server (bsc#1089987).
• CVE-2018-2782: Vulnerability in the MySQL Server component of Oracle
  MySQL (subcomponent: InnoDB). Easily exploitable vulnerability allowed
  low privileged attacker with network access via multiple protocols to
  compromise MySQL Server. Successful attacks of this vulnerability can
  result in unauthorized ability to cause a hang or frequently repeatable
  crash (complete DOS) of MySQL Server (bsc#1089987, bsc#1090518).
• CVE-2018-2784: Vulnerability in the MySQL Server component of Oracle
  MySQL (subcomponent: InnoDB). Easily exploitable vulnerability allowed
  low privileged attacker with network access via multiple protocols to
  compromise MySQL Server. Successful attacks of this vulnerability can
  result in unauthorized ability to cause a hang or frequently repeatable
  crash (complete DOS) of MySQL Server (bsc#1089987, bsc#1090518).
• CVE-2018-2787: Vulnerability in the MySQL Server component of Oracle
  MySQL (subcomponent: InnoDB). Easily exploitable vulnerability allowed
  high privileged attacker with network access via multiple protocols to
  compromise MySQL Server. Successful attacks of this vulnerability can
  result in unauthorized ability to cause a hang or frequently repeatable
  crash (complete DOS) of MySQL Server as well as unauthorized update,
  insert or delete access to some of MySQL Server accessible data
  (bsc#1089987, bsc#1090518).
• CVE-2018-2766: Vulnerability in the MySQL Server component of Oracle
  MySQL (subcomponent: InnoDB). Easily exploitable vulnerability allowed
  high privileged attacker with network access via multiple protocols to
  compromise MySQL Server. Successful attacks of this vulnerability can
  result in unauthorized ability to cause a hang or frequently repeatable
  crash (complete DOS) of MySQL Server (bsc#1089987, bsc#1090518).
• CVE-2018-2755: Vulnerability in the MySQL Server component of Oracle
  MySQL (subcomponent: Server: Replication). Difficult to exploit
  vulnerability allowed unauthenticated attacker with logon to the
  infrastructure where MySQL Server executes to compromise MySQL Server.
  Successful attacks require human interaction from a person other than
  the attacker and while the vulnerability is in MySQL Server, attacks may
  significantly impact additional products. Successful attacks of this
  vulnerability can result in takeover of MySQL Server (bsc#1089987,
  bsc#1090518).
• CVE-2018-2819: Vulnerability in the MySQL Server component of Oracle
  MySQL (subcomponent: InnoDB). Easily exploitable vulnerability allowed
  low privileged attacker with network access via multiple protocols to
  compromise MySQL Server. Successful attacks of this vulnerability can
  result in unauthorized ability to cause a hang or frequently repeatable
  crash (complete DOS) of MySQL Server (bsc#1089987, bsc#1090518).
• CVE-2018-2817: Vulnerability in the MySQL Server component of Oracle
  MySQL (subcomponent: Server: DDL). Easily exploitable vulnerability
  allowed low privileged attacker with network access via multiple
  protocols to compromise MySQL Server. Successful attacks of this
  vulnerability can result in unauthorized ability to cause a hang or
  frequently repeatable crash (complete DOS) of MySQL Server (bsc#1089987,
  bsc#1090518).
• CVE-2018-2761: Vulnerability in the MySQL Server component of Oracle
  MySQL (subcomponent: Client programs). Difficult to exploit
  vulnerability allowed unauthenticated attacker with network access via
  multiple protocols to compromise MySQL Server. Successful attacks of
  this vulnerability can result in unauthorized ability to cause a hang or
  frequently repeatable crash (complete DOS) of MySQL Server (bsc#1089987,
  bsc#1090518).
• CVE-2018-2781: Vulnerability in the MySQL Server component of Oracle
  MySQL (subcomponent: Server: Optimizer). Easily exploitable
  vulnerability allowed high privileged attacker with network access via
  multiple protocols to compromise MySQL Server. Successful attacks of
  this vulnerability can result in unauthorized ability to cause a hang or
  frequently repeatable crash (complete DOS) of MySQL Server (bsc#1089987,
  bsc#1090518).
• CVE-2018-2771: Vulnerability in the MySQL Server component of Oracle
  MySQL (subcomponent: Server: Locking). Difficult to exploit
  vulnerability allowed high privileged attacker with network access via
  multiple protocols to compromise MySQL Server. Successful attacks of
  this vulnerability can result in unauthorized ability to cause a hang or
  frequently repeatable crash (complete DOS) of MySQL Server (bsc#1089987,
  bsc#1090518).
• CVE-2018-2813: Vulnerability in the MySQL Server component of Oracle
  MySQL (subcomponent: Server: DDL). Easily exploitable vulnerability
  allowed low privileged attacker with network access via multiple
  protocols to compromise MySQL Server. Successful attacks of this
  vulnerability can result in unauthorized read access to a subset of
  MySQL Server accessible data (bsc#1089987, bsc#1090518).

These non-security issues were fixed:

• PCRE updated to 8.42
• Incomplete validation of missing tablespace during recovery
• ib_buffer_pool unnecessarily includes the temporary tablespace
• InnoDB may write uninitialized garbage to redo log
• Virtual Columns: Assertion failed in dict_table_get_col_name
• slow innodb startup/shutdown can exceed systemd timeout
• Assertion failed in dict_check_sys_tables on upgrade from 5.5
• Change buffer crash during TRUNCATE or DROP TABLE
• temporary table ROLLBACK fixes
