RHEL 3 : mysql-server (RHSA-2004:611)

Synopsis :

The remote Red Hat host is missing a security update.

Description :

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 Network.

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.
