RHSA-2004-611: mysql

Vulnerability Assessment Summary
Check for the version of the mysql packages

Detailed Explanation for this Vulnerability Assessment

An updated mysql-server package that fixes various security issues is now
available in the Red Hat Enterprise Linux 3 Extras channel of Red Hat

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

A number of security issues that affect the mysql-server package have been
reported. Although Red Hat Enterprise Linux 3 does not ship with the
mysql-server package, the affected package is available from the Red Hat
Network Extras channel.

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 ( has assigned
the name CVE-2004-0835 to this issue.

Lukasz Wojtow discovered a buffer overrun in the mysql_real_connect
function. In order to exploit this issue a possible hacker would need to force
the use of a malicious DNS server (CVE-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 (CVE-2004-0837).

Sergei Golubchik discovered that if a user is granted rights to a
database with a name containing an underscore ("_"), the user also gains
the ability to grant rights to other databases with similar names

Users of mysql-server should upgrade to these erratum packages, which
correct these issues.
