Serious bug in smarty if safe mode and open basedir set

Hi! (This is my frirst letter, sorry my english... :) ) I find a bug isn Smarty.class.php: I work with php in safe mode, and i set the open basedir in apache config in my virtual host config php_admin_value open_basedir .:/home/donci/public_html/pentzadmin/: /home/donci/public_html/pentz/: /home/donci/public_html/PHP/: /home/donci/tmp/smarty/ (I put spaces this line to correct wordwrap). My smarty compile dir is set by define( 'SMARTY_COMPILEDIR', '/home/donci/tmp/smarty/' ); $smarty->compile_dir = SMARTY_COMPILEDIR . 'templates_c'; This dir is in open basedir path. There is the bug: if there are new template, smarty probes make new dirs in /home/donci/tmp/smarty/ (for example: %%-143/%%883838) The _create_dir_structure($dir) function is wrond, because it probes make dir, like: is_dir /home -> ok then is_dir /home/donci .. is dir /home/donci/tmp/smarty/%-143 ->no mkdir /home/donci/tmp/smarty/%-143 But in safe mode the is_dir /home is not allowed... (is_dir /home/donci/tmp/smarty/ allowed.) my patch that corrects this error is: function _create_dir_structure($dir) { if ( !@is_dir( $dir ) ) { $dir_parts = preg_split('!\\'.DIR_SEP.'+!', $dir, -1, PREG_SPLIT_NO_EMPTY); $dirdepth = sizeof( $dir_parts); $depth = $dirdepth; while( $depth > 1 and $depth <= $dirdepth ) { $dirparts = array_slice( $dir_parts, 0, $depth ); $new_dir = DIR_SEP . implode( DIR_SEP , $dirparts ); if ( @mkdir($new_dir) ) { $depth++; } else { $depth--; } } if ( $depth < $dirdepth ) { $this->trigger_error('problem creating directory "' . $dir . '"'); return false; } } } This patch make directories in reverse order, and makes fewer dir examination. bye! Den
