|
Status: Closed |
USING DEFAULT VALUES FOR LVARCHAR STORED PROCEDURE PARAMETER CAUSES MEMORY CORRUPTION |
| product: |
IBM IDS ENTRP E / 5724L2304 / B15 - IDS 11.50 |
| Problem description: |
Default values used for lvarchar stored procedure parameters
cause memory corruption leading to assertion failures. The
assertion failure stack traces vary. They occur any time from
immediately after the memory corruption to the end of the
session. |
| Problem Summary: |
****************************************************************
USERS AFFECTED:
All the Informix Dynamic Server (IDS) 11.50 users
****************************************************************
PROBLEM DESCRIPTION:
The create procedure can corrupt memory when the procedure has
input arguments as lvarachar with default values. The problem
occurs while preparing the record that will be inserted in the
sysdefaults catalog table. The IDS was not setting the right
length for the default value string and due to this the values
were overwrtting.
****************************************************************
RECOMMENDATION:
Upgrade to 11.50.xc2 or above.
