Description

LSAC(v2)
MySQL is a multi-user, multi-threaded SQL database server. It consists of the MySQL server daemon (mysqld) and many client programs and libraries. It was found that the fix for the CVE-2009-4030 issue, a flaw in the way MySQL checked the paths used as arguments for the DATA DIRECTORY and INDEX DIRECTORY directives when the "datadir" option was configured with a relative path, was incorrectly removed when the mysql packages in Red Hat Enterprise Linux 5 were updated to version 5.0.95 via RHSA-2012:0127. An authenticated attacker could use this flaw to bypass the restriction preventing the use of subdirectories of the MySQL data directory being used as DATA DIRECTORY and INDEX DIRECTORY paths. This update re-applies the fix for CVE-2009-4030. (CVE-2012-4452) Note: If the use of the DATA DIRECTORY and INDEX DIRECTORY directives were disabled as described in RHSA-2010:0109 (by adding "symbolic-links=0" to the "[mysqld]" section of the "my.cnf" configuration file), users were not vulnerable to this issue. This issue was discovered by Karel Volný of the Red Hat Quality Engineering team. This update also fixes the following bugs: * Prior to this update, the log file path in the logrotate script did not behave as expected. As a consequence, the logrotate function failed to rotate the "/var/log/mysqld.log" file. This update modifies the logrotate script to allow rotating the mysqld.log file. (BZ#647223) * Prior to this update, the mysqld daemon could fail when using the EXPLAIN flag in prepared statement mode. This update modifies the underlying code to handle the EXPLAIN flag as expected. (BZ#654000) * Prior to this update, the mysqld init script could wrongly report that mysql server startup failed when the server was actually started. This update modifies the init script to report the status of the mysqld server as expected. (BZ#703476) * Prior to this update, the "--enable-profiling" option was by default disabled. This update enables the profiling feature. (BZ#806365) All MySQL users are advised to upgrade to these updated packages, which contain backported patches to resolve these issues. After installing this update, the MySQL server daemon (mysqld) will be restarted automatically.
