ID: 26042 Updated by: [EMAIL PROTECTED] Reported By: vsv3 at alu dot ua dot es -Status: Feedback +Status: Verified Bug Type: mcrypt related Operating System: Linux 2.4.22 Debian Woody PHP Version: 4.3.2 New Comment:
Looks like a leak starting in mcrypt_generic_init(). When mcrypt_generic_init() is called from PHP userland, it never gets deinit'd unless you explicitly call mcrypt_generic_deinit(). Perhaps mcrypt_generic_init() should check to see if the td has already been init'd and if so, deinit it first. Haven't looked too closely at the libmcrypt source yet to see the easiest way to do it. This is using libmcrypt 2.5.7 and an up-to-date 4_3.

It gets more and more memory. Reproduce code: --------------- <?php $key = '123456789012345678901234567890'; $iv = '12345678'; $nVeces = 100000; $n = 0; $td = mcrypt_module_open( MCRYPT_BLOWFISH, '', MCRYPT_MODE_CBC, '' ); while( $n < $nVeces ) { $fichero = file_get_contents( "/tmp/hola" ); mcrypt_generic_init( $td, $key, $iv ); $fichero_enc = addslashes( mcrypt_generic($td, $textoPlano) ); unset( $fichero_enc ); if( isset($fichero_enc) ) echo "<b><h1>No pudimos destruir la variable</h1></b><br />"; $n = $n + 1; } mcrypt_module_close( $td ); ?> Expected result: ---------------- A script that execute with a consume of less than 1MB of memory (with a file '/tmp/hola' of 1kB). Actual result: -------------- An script that consumes more than 100MB, or more. A similar script with other data, have been consumed more than 2000MB. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=26042&edit=1
