Updated mysql packages that fix a temporary file flaw and a number of bugs are now available. This update has been rated as having low security impact by the CentOS 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. An insecure temporary file handling bug was found in the mysql_install_db script. It is possible for a local user to create specially crafted files in /tmp which could allow them to execute arbitrary SQL commands during database installation. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-1636 to this issue. These packages update mysql to version 4.1.12, fixing a number of problems. Also, support for SSL-encrypted connections to the database server is now provided. All users of mysql are advised to upgrade to these updated packages.
