Description

Several issues have been discovered in the MySQL database server. The vulnerabilities are addressed by upgrading MySQL to a new upstream version, 5.5.33, which includes additional changes, such as performance improvements, bug fixes, new features, and possibly incompatible changes. Please see the MySQL 5.5 Release Notes for further details:

http://dev.mysql.com/doc/relnotes/mysql/5.5/en/news-5-5-32.htmlhttp://dev.mysql.com/doc/relnotes/mysql/5.5/en/news-5-5-33.html In addition this update fixes two issues affecting specifically the mysql-5.5 Debian package:

A race condition in the post-installation script of the mysql-server-5.5 package creates the configuration file /etc/mysql/debian.cnf with world-readable permissions before restricting the permissions, which allows local users to read the file and obtain sensitive information such as credentials for the debian-sys-maint to perform administration tasks. (CVE-2013-2162 )

Matthias Reichl reported that the mysql-5.5 package misses the patches applied previous in Debian's mysql-5.1 to drop the database test and the permissions that allow anonymous access, without a password, from localhost to the test database and any databases starting with test_ . This update reintroduces these patches for the mysql-5.5 package.

Existing databases and permissions are not touched. Please refer to the NEWS file provided with this update for further information.
