PHP Bug Type: mcrypt related
Bug description: calling mcrypt after mcrypt_generic_deinit crashes
Description:
------------
In bug # 41252, it was observed that, in PHP4, calling mcrypt_generic()
before calling mcrypt_module_open() would cause PHP4 to crash. PHP5
apparently had extra checks to protect against this that were backported.
These extra checks, however, do not appear to be sufficient, as the
following reproduce code demonstrates.
Sure, calling mcrypt_generic_deinit() before calling mcrypt_generic is
probably not something you ought to be doing, anyway, but I still don't
think it ought to crash PHP.
Reproduce code:
---------------
<?php
$td = mcrypt_module_open(MCRYPT_DES, '', MCRYPT_MODE_ECB, '');
mcrypt_generic_init($td, 'aaaaaaaa', 'aaaaaaaa');
mcrypt_generic_deinit($td);
echo mcrypt_generic($td, 'aaaaaaaa');
?>
Expected result:
----------------
Warning: mcrypt_generic(): Operation disallowed prior to
mcrypt_generic_init() in {filename} on line 5
Actual result:
--------------
It crashes.
