DESCRIPTION
 "mod_auth_mysql" is an authentication module for apache which
 authenticates users against a MySQL database.
 RUS-CERT[3] discovered a vulnerability[1][2] in several Apache
 authentication modules which use SQL databases to retrieve user
 information. This vulnerability allows a remote attacker to change
 the query that the module sends to the SQL server and potentially
 circumvent the authentication process.
 The mysql_query() function, used by this module, does not allow
 multiple commands do be sent to the server, that is, the ";"
 character is not allowed. This restricts this vulnerability somewhat,
 since the attacker can no longer issue other commands besides the
 SELECT one the module is already doing, but he/she can still mangle
 this query and this should not be underestimated.
 Additionally, this update also fixes a problem with this package
 which wasn't linked against the MySQL libraries in previous releases.


SOLUTION
 All mod_auth_mysql users should upgrade.
 
 IMPORTANT: it is necessary to restart the apache server after
 applying the update.
