RHSA-2003:094 - Security Advisory

Topic

Updated packages are available that fix both a double-free security
vulnerability and a remote root exploit security vulnerability found in the
MySQL server.

[Updated 11 Aug 2003]
Updated mysqlclient9 packages are now included. These were previously
missing from this erratum.

Description

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

A double-free vulnerability in mysqld, for MySQL before version 3.23.55,
allows attackers with MySQL access to cause a denial of service (crash) by
creating a carefully crafted client application.

A remote root exploit vulnerability in mysqld, for MySQL before version
3.23.56, allows MySQL users to gain root privileges by overwriting
configuration files.

Previous versions of the MySQL packages do not contain the thread safe
client library (libmysqlclient_r).

All users of MySQL are advised to upgrade to these errata packages
containing MySQL 3.23.56.

Before applying this update, make sure all previously released errata
