mysql security update

Updated mysql packages that fix several vulnerabilities are now available.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

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

This update fixes several security risks in the MySQL server.

Stefano Di Paola discovered two bugs in the way MySQL handles user-defined
functions. A user with the ability to create and execute a user defined
function could potentially execute arbitrary code on the MySQL server. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the names CAN-2005-0709 and CAN-2005-0710 to these issues.

Stefano Di Paola also discovered a bug in the way MySQL creates temporary
tables. A local user could create a specially crafted symlink which could
result in the MySQL server overwriting a file which it has write access to.
The Common Vulnerabilities and Exposures project has assigned the name
CAN-2005-0711 to this issue.

All users of the MySQL server are advised to upgrade to these updated
packages, which contain fixes for these issues.
