Bug #37620 mysqli_ssl_set validation is innappropriate
Submitted: 2006-05-29 01:43 UTC Modified: 2006-05-29 05:39 UTC
From: ap at zip dot com dot au Assigned: georg
Status: Closed Package: MySQLi related
PHP Version: 5.1.4 OS: Linux
Private report: No CVE-ID:
 [2006-05-29 01:43 UTC] ap at zip dot com dot au
Description:
------------
When the validation code was introduced to fix bug #36802 a seemingly blind change was made to all (probably - I did not count :) the functions to validate against MYSQLI_STATUS_VALID as can be seen here: 

http://cvs.php.net/viewcvs.cgi/php-src/ext/mysqli/mysqli_api.c?r1=1.118.2.18&r2=1.118.2.19

This doesn't work for mysqli_ssl_set as it needs to be called before a connection to the mysql server is made and as such, judging by the documentation here:

http://cvs.php.net/viewcvs.cgi/php-src/ext/mysqli/mysqli_api.c?view=log#rev1.118.2.19

MYSQLI_STATUS_INITIALIZED appears to be a better test to validate against.

Have patch. Hopefully will be able to attach it once I submit it.


Reproduce code:
---------------
$db = mysqli_init();
mysqli_ssl_set($db,$key, $cert, $cacert, NULL,NULL);
exit;


Expected result:
----------------
*nothing*

Actual result:
--------------
Warning: mysqli_ssl_set(): invalid object or resource mysqli in test.php on line 5
