(RHSA-2004:597) mysql security update

MySQL is a multi-user, multi-threaded SQL database server.

A number security issues that affect the mysql server have been reported:

Oleksandr Byelkin discovered that “ALTER TABLE … RENAME” checked
the CREATE/INSERT rights of the old table instead of the new one. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the name CAN-2004-0835 to this issue.

Lukasz Wojtow discovered a buffer overrun in the mysql_real_connect
function. In order to exploit this issue an attacker would need to force
the use of a malicious DNS server (CAN-2004-0836).

Dean Ellis discovered that multiple threads ALTERing the same (or
different) MERGE tables to change the UNION could cause the server to crash
or stall (CAN-2004-0837).

Sergei Golubchik discovered that if a user is granted privileges to a
database with a name containing an underscore (“_”), the user also gains
the ability to grant privileges to other databases with similar names
(CAN-2004-0957).

Additionally, the following minor temporary file vulnerabilities were
discovered:

• Stan Bubroski and Shaun Colley found a temporary file vulnerability in
  the mysqlbug script (CAN-2004-0381).
• A temporary file vulnerability was discovered in mysqld_multi
  (CAN-2004-0388).
• Jeroen van Wolffelaar discovered an temporary file vulnerability in the
  mysqlhotcopy script when using the scp method (CAN-2004-0457).

All users of mysql should upgrade to these updated packages, which resolve
these issues and also include fixes for a number of small bugs.
