Hi all,

We are using Sandesha2/C client in our product for WS-RM capability. While
testing the standalone sample program for sandesha2/c for sending 200
messages (basic echo message), we could see crash consistently at following
location after lot of debugging.

file - src/storage/sqlite/permanent_seq_property_mgr.c +344

axis2_bool_t AXIS2_CALL
sandesha2_permanent_seq_property_mgr_update(
    sandesha2_seq_property_mgr_t *seq_prop_mgr,
    const axutil_env_t *env,
    sandesha2_seq_property_bean_t *bean)
{
    axis2_char_t sql_update[1024];
    axis2_bool_t ret = AXIS2_FALSE;
    axis2_char_t *id = NULL;
    sandesha2_permanent_seq_property_mgr_t *seq_prop_mgr_impl = NULL;
    axis2_char_t *seq_id = NULL;
    axis2_char_t *name = NULL;
    axis2_char_t *value    = NULL;

    AXIS2_PARAM_CHECK(env->error, bean, AXIS2_FALSE);

    id = sandesha2_permanent_seq_property_mgr_get_id_with_bean(env, bean);
    seq_id = sandesha2_seq_property_bean_get_seq_id(bean, env);
    name = sandesha2_seq_property_bean_get_name(bean, env);
    value = sandesha2_seq_property_bean_get_value(bean, env);

    seq_prop_mgr_impl = SANDESHA2_INTF_TO_IMPL(seq_prop_mgr);

    sprintf(sql_update, "update seq_property set seq_id='%s', name='%s',"\
        "value='%s' where id='%s'", seq_id, name, value, id);
    if(id)
        AXIS2_FREE(env->allocator, id);
    ret = sandesha2_permanent_bean_mgr_update(seq_prop_mgr_impl->bean_mgr,
env,
        sql_update);
    return ret;
}


Crash seen at sprintf line.

sql_update variable size is fixed as 1024.  After certain number of
messages (in our case, 176 messages exactly), sprintf crashes with buffer
overflow as value is keep appending the messages number (it grows as we
continue further).

I hope I made everything clear. Now, i want to know whether this is known
issue which got fixed or if not, can anybody fix this ?

Unfortunately, for 0.91 version (which is downloadable from apache website)
there is no provision for inmemory storage mgr (to use it as alternative
case), as code is hard coded to persistence based storage mgr.
