Subject: netgroup: nis in nsswitch.conf causes libc6 to fail and programs like sudo or rpc.mountd to crash

Date: Tue, 30 May 2006 15:33:21 +0200

Package: libc6
Version: 2.3.6-9
Severity: important


if in /etc/nsswitch.conf:

netgroup:       nis


then e.g. sudo fails:

vsauer@gelnhausen: ~ > sudo bash
sudo: nss_nis/nis-netgrp.c:78: _nss_nis_setnetgrent: Assertion `len > 0' failed

and rpc.mountd fails with the same error.

If I set

netgroup: files

everything runs okay.

Package: libc6
Version: 2.3.6-15
Followup-For: Bug #369536


Kubuntu Dapper Drake is affected, too.
They are using libc6 version: 2.3.6-0ubuntu20

And: Hey guys!! This is a severe bug for those who use debian clients in a network of NIS-computers!! This is very common and therefore this bug needs to be fixed!!!!!

Subject: cfengine2 triggers libc6 bug

Date: Thu, 30 Nov 2006 16:12:11 -0700

I found another command that triggers this bug.   

Running the command: "CFINPUTS=/usr/config/cfinputs 
/opt/cfengine/sbin/cfengine --dry-run --no-splay -DHr20 -v"

Results:  program aborts midway when the netgroup is delivered by NIS.  
(netgroup: nis  is set in nsswitch.conf)

   As mentioned above, if "netgroup: files"  is set in nsswitch.conf 
the problem isn't triggered.

Key Error Message: " cfengine: nss_nis/nis-netgrp.c:78: 
_nss_nis_setnetgrent: Assertion `len > 0' failed. "

This bug is about the NIS netgroup map, the others are about the
group map. Unmerging.

This particular bug is a duplicate of
	http://bugs.gentoo.org/show_bug.cgi?id=96370
which was resolved (upstream) long ago. Basically, the assert(len > 0) 
on line 78 of nss_nis/nis-netgrp.c should read assert(len >= 0).
A real shame that this made it into etch.

  Indeed this is fixed in glibc2.5

  This remark is greatly appreciated.


  A real shame you hibernated until now.

I confirm that the bug has been fixed in glibc 2.5, I am therefore
marking the bug closed by this new version.

I will try to get this patch in the next stable update.

Thank you. For those who can't wait, it should perhaps be mentioned
that the bug can be worked around by not having empty netgroups in
one's map.
