mysql-dfsg-5.0 - authorization bypass

Sergei Golubchik discovered that MySQL, a widely-deployed database
server, did not properly validate optional data or index directory
paths given in a CREATE TABLE statement, nor would it (under proper
conditions) prevent two databases from using the same paths for data
or index files. This permits an authenticated user with authorization
to create tables in one database to read, write or delete data from
tables subsequently created in other databases, regardless of other
GRANT authorizations. The Common Vulnerabilities and Exposures
project identifies this weakness as CVE-2008-2079.

For the stable distribution (etch), this problem has been fixed in
version 5.0.32-7etch6. Note that the fix applied will have the
consequence of disallowing the selection of data or index paths
under the database root, which on a Debian system is /var/lib/mysql;
database administrators needing to control the placement of these
files under that location must do so through other means.

We recommend that you upgrade your mysql-dfsg-5.0 packages.
