Description Jaroslaw Sosnicki 1999-04-14 23:51:17 EDT
When I upgraded from 5.9.8.1 to 5.9.9 I am getting
Segmentation fault when using su - username logged in as
root.
I can do as root: su userid without errors, also I can do
su - userid form other users without errors.

Lookus like a bug to me...
Comment 1 Michael K. Johnson 1999-04-15 11:37:59 EDT
I've fixed a lot of potential segfaults (including some we saw
happen) in the pam_xauth module that is included in pam-0.66-14
and I'm not able to reproduce this, so I will assume that this
is fixed.  If this was happening in X, then I probably fixed it;
if it was happening from the console, then I almost assuredly
fixed it.

If you can reproduce this bug with pam-0.66-14 or later, please
reopen this bug with the version of pam you are using, the version
of sh-utils, and the output of the env command before running the
su - username
Thanks!

Where do I find pam-0.66-14...

It is not part of 5.9.9
Comment 3 Michael K. Johnson 1999-04-17 12:29:59 EDT
There were two bugs, one hiding the other.  The one was fixed in
0.66-14, the other in 0.66-15.
