Description Michael Hill 2004-08-28 23:00:18 MDT

I just upgraded to 1.6.8 (built the RPM myself)--previous versions worked fine.
 When I run sudo as a normal user listed in the sudoers file, it segfaults after
I type in my password.  It does not log the attempt in the sudo.log file.  It
runs normally when run as root (doesn't prompt for a password).  When I add
NOPASSWD to my user line in sudoers, it runs normally.  So I believe the
(mis)behavior is related to the password checking.  I use the sample.pam file,
unchanged, in /etc/pam.d/sudo .

Do you have any Defaults variables set in sudoers?  If so, please let me know which ones.

Comment 2 Michael Hill 2004-08-29 07:26:02 MDT

No, I don't.  The only non-blank, non-comment lines are entries for my main id
and root.

Thanks, Todd.  That worked a charm!  Will you be rolling out a patched tarball,
or should I just update my package build?

Comment 6 Todd C. Miller 2004-08-30 13:19:22 MDT

I'm waiting on an LDAP fix, after which I will roll out patch1 for sudo 1.6.8.  In the meantime I suggest 
you simply update your package build.

The updated sample.pam file shipped with sudo 1.6.8p1
