mysql security update

CentOS Errata and Security Advisory CESA-2007:1222-001

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 found in a way MySQL handled symbolic links when database tables
were created with explicit “DATA” and “INDEX DIRECTORY” options. An
authenticated user could create a table that would overwrite tables in
other databases, causing destruction of data or allowing the user to
elevate privileges. (CVE-2007-5969)

A flaw was found in a way MySQL’s InnoDB engine handled spatial indexes. An
authenticated user could create a table with spatial indexes, which are not
supported by the InnoDB engine, that would cause the mysql daemon to crash
when used. This issue only causes a temporary denial of service, as the
mysql daemon will be automatically restarted after the crash.
(CVE-2007-5925)

A flaw was found in a way MySQL handled the “DEFINER” view parameter. A
user with the “ALTER VIEW” privilege for a view created by another database
user, could modify that view to get access to any data accessible to the
creator of said view. (CVE-2007-6303)

All mysql users are advised to upgrade to these updated packages, which
contain backported patches to resolve these issues.
