CESA-2004:597: mysql security update



Updated mysql packages that fix various security issues, as well as a number of bugs, are now available for CentOS Linux 2.1.

MySQL is a multi-user, multi-threaded SQL database server. A number security issues that affect the mysql server have been reported: Oleksandr Byelkin discovered that "ALTER TABLE ... RENAME" checked the CREATE/INSERT rights of the old table instead of the new one. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0835 to this issue. Lukasz Wojtow discovered a buffer overrun in the mysql_real_connect function. In order to exploit this issue an attacker would need to force the use of a malicious DNS server (CAN-2004-0836). Dean Ellis discovered that multiple threads ALTERing the same (or different) MERGE tables to change the UNION could cause the server to crash or stall (CAN-2004-0837). Sergei Golubchik discovered that if a user is granted privileges to a database with a name containing an underscore ("_"), the user also gains the ability to grant privileges to other databases with similar names (CAN-2004-0957). Additionally, the following minor temporary file vulnerabilities were discovered: - Stan Bubroski and Shaun Colley found a temporary file vulnerability in the mysqlbug script (CAN-2004-0381). - A temporary file vulnerability was discovered in mysqld_multi (CAN-2004-0388). - Jeroen van Wolffelaar discovered an temporary file vulnerability in the mysqlhotcopy script when using the scp method (CAN-2004-0457). All users of mysql should upgrade to these updated packages, which resolve these issues and also include fixes for a number of small bugs.
