Description Kambiz Aghaiepour 2001-10-03 15:21:40 EDT

From Bugzilla Helper:
User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.4.3-12 i686)

Description of problem:
Bad config file parameter to pam_listfile.so, specifically space after
"file=" parameter, causes application SEGV.


Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.  Installed vsftpd
2.  In /etc/pam.d/ftp, have the auth line:
   auth  required  /lib/security/pam_listfile.so item=user sense=deny file=
/etc/ftpusers onerr=succeed

(notice the <SPACE> after "file=")

3.  ftp to server and try anonymous ftp

	

Additional info:

I'm not sure if this is a problem in vsftpd or in pam_listfile.  I also
have not tried this in 7.x series.  Let me know if you'd like me to.

Comment 1 Nalin Dahyabhai 2002-03-07 19:23:58 EST

This should be one of the bugs fixed in the current errata release for RHL 7.2,
so I'm marking this as fixed in the current release.  Because you'd have to
configure it incorrectly to cause it to crash, I don't think it warrants an
erratum at this time.
