Description Catalin Patulea 2006-10-23 06:04:53 UTC 
When innetgr() is called with ("group", NULL, "user", NULL), the program
segfaults because of a strdup(NULL).

See https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=208718.
Comment 1 Jakub Jelinek 2006-10-23 07:10:46 UTC 
This is already fixed on glibc trunk:
2006-10-10  Ulrich Drepper  <drepper@redhat.com>

        * nis/nis_subr.c (nis_getnames): Add trailing dot to NIS_PATH
        components which lack them.

        * nis/nis_subr.c (nis_getnames): Make sure that we always return
        at least one entry consisting of the parameter concatenated with
        the domain.
and is planned soon for glibc-2_5-branch.
