MySQL Bugs: #7291: Stored procedures: wrong CURRENT

Bug #7291	Stored procedures: wrong CURRENT_USER value
Submitted:	14 Dec 2004 18:35	Modified:	17 Jul 2005 2:47
Reporter:	Peter Gulutzan
Status:	Closed
Category:	Server	Severity:	S3 (Non-critical)
Version:	5.0.3-alpha-debug	OS:	Linux (SUSE 9.2)
Assigned to:	Oleksandr Byelkin	Target Version:

Description:
If a stored procedure characteristic is SQL SECURITY DEFINER, 
then CURRENT_USER should be the "routine authorization" user, 
which in MySQL's case is the creator of the procedure. 
But instead, CURRENT_USER is the user who CALLs the procedure. 
 

How to repeat:
As user root, say: 
 
mysql> create procedure p () sql security definer select current_user; 
Query OK, 0 rows affected (0.05 sec) 
 
As user pierre, who has been granted ALL PRIVILEGES in the database 
that procedure p is in, say: 
 
mysql> call p(); 
+--------------+ 
| current_user | 
+--------------+ 
| pierre@%     | 
+--------------+ 
1 row in set (0.00 sec) 
 
Query OK, 0 rows affected (0.00 sec)
