Package: libapache2-mod-vhost-ldap
Version: 0.2.3-1
Severity: important

mod-vhost-ldap segfaults when used with the Apache2 worker MPM, with 
suExec and cgid enabled. (The Debian packages ensure cgid is used 
with the worker MPM.)

Here is a gdb backtrace, suitably cut:

(gdb) bt
#0  0x405d0e8c in mod_vhost_ldap_get_suexec_id_doer (r=0x818e0b8)
    at mod_vhost_ldap.c:468
#1  0x08095a85 in ap_run_get_suexec_identity ()
#2  0x08095c85 in ap_os_create_privileged_process ()
#3  0x40586506 in ?? () from /usr/lib/apache2/modules/mod_cgid.so

The module tries to do

mod_vhost_ldap_config_t *cfg =
  (mod_vhost_ldap_config_t *)ap_get_module_config(r->server->module_config,
                                                  &vhost_ldap_module);

Which fails because r->server->module_config is null. At least I think 
that's why it fails.

(gdb) print r->server->module_config
$1 = (struct ap_conf_vector_t *) 0x0

I'm trying to figure out what this means, just recording this here.

I've verified that this has been fixed upstream and that this fix is
indeed in the current Debian package. I'm closing this bug.

Thanks for reporting.
