The remote host is missing updates announced in
advisory RHSA-2004:611.
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 (cve.mitre.org) 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 an attacker 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 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
(CVE-2004-0957).
Users of mysql-server should upgrade to these erratum packages, which
correct these issues.
Solution:
Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
