Updated mysql packages that fix a security flaw are now available for Red
Hat Enterprise Linux 4 and 5.
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. MySQL is a
client/server implementation consisting of a server daemon (mysqld) and
many different client programs and libraries.
A flaw was discovered in MySQL's authentication protocol. It is possible
for a remote unauthenticated attacker to send a specially crafted
authentication request to the MySQL server causing it to crash. (CVE-2007-3780)
All users of the MySQL server are advised to upgrade to these updated
packages, which contain a backported patch which fixes this issue.
