Mandriva: Updated mysql packages fix vulnerabilities
LinuxSecurity.com: Multiple buffer overflows in yaSSL, which is used in MySQL, allowed remote attackers to execute arbitrary code (CVE-2008-0226) or cause a denial of service via a special Hello packet (CVE-2008-0227). Sergei Golubchik found that MySQL did not properly validate optional data or index directory paths given in a CREATE TABLE statement; as well it would not, under certain conditions, prevent two databases from using the same paths for data or index files. This could allow an authenticated user with appropriate privilege to create tables in one database to read and manipulate data in tables later created in other databases, regardless of GRANT privileges (CVE-2008-2079). The updated packages have been patched to correct these issues.

cgi::session::driver::mysql

CGI::Session::Driver::mysql(3)				User Contributed Perl Documentation			    CGI::Session::Driver::mysql(3)

NAME

       CGI::Session::Driver::mysql - CGI::Session driver for MySQL database

SYNOPSIS

	   $s = new CGI::Session( 'driver:mysql', $sid);
	   $s = new CGI::Session( 'driver:mysql', $sid, { DataSource  => 'dbi:mysql:test',
							  User	      => 'sherzodr',
							  Password    => 'hello' });
	   $s = new CGI::Session( 'driver:mysql', $sid, { Handle => $dbh } );

DESCRIPTION

       mysql stores session records in a MySQL table. For details see CGI::Session::Driver::DBI, its parent class.

       It's especially important for the MySQL driver that the session ID column be defined as a primary key, or at least "unique", like this:

	CREATE TABLE sessions (
	    id CHAR(32) NOT NULL PRIMARY KEY,
	    a_session TEXT NOT NULL
	 );

       To use different column names, change the 'create table' statement, and then simply do this:

	   $s = new CGI::Session('driver:mysql', undef,
	   {
	       TableName=>'session',
	       IdColName=>'my_id',
	       DataColName=>'my_data',
	       DataSource=>'dbi:mysql:project',
	   });

       or

	   $s = new CGI::Session('driver:mysql', undef,
	   {
	       TableName=>'session',
	       IdColName=>'my_id',
	       DataColName=>'my_data',
	       Handle=>$dbh,
	   });

   DRIVER ARGUMENTS
       mysql driver supports all the arguments documented in CGI::Session::Driver::DBI. In addition, DataSource argument can optionally leave
       leading "dbi:mysql:" string out:

	   $s = new CGI::Session( 'driver:mysql', $sid, {DataSource=>'shopping_cart'});
	   # is the same as:
	   $s = new CGI::Session( 'driver:mysql', $sid, {DataSource=>'dbi:mysql:shopping_cart'});

   BACKWARDS COMPATIBILITY
       As of V 4.30, the global variable $CGI::Session::MySQL::TABLE_NAME cannot be used to set the session table's name.

       This is due to changes in CGI::Session::Driver's new() method, which now allows the table's name to be changed (as well as allowing both
       the 'id' column name and the 'a_session' column name to be changed).

       See the documentation for CGI::Session::Driver::DBI for details.

       In particular, the new syntax for "new()" applies to all database drivers, whereas the old - and bad - global variable method only applied
       to MySQL.

       Alternately, call $session -> table_name('new_name') just after creating the session object if you wish to change the session table's name.
