Description:
------------
In odbc_stmt.c, in functions odbc_stmt_set_param(), line 766 and 
odbc_stmt_get_attr(), line 798, error code "IM0001" is placed in the 
(pdo_odbc_stmt *)S->einfo.last_state.

The length of this error code string ("IM0001") is 7 bytes, but 
last_state field declared as (php_pdo_odbc_int.h, line 121):
char last_state[6].

So buffer overflow will happen when executing
'strcpy(S->einfo.last_state, "IM0001")'.

Comparing to other PDO drivers it seems that error code should be 5 
char in length, i.e. "IM001".
