Description Dan Book 2010-05-10 15:53:10 UTC
Description of problem:
After updating the packages nss-softokn and nss-softokn-freebl on my server to 3.12.4-17.fc12 I discovered I was unable to log in via SSH, FTP or the console provided by the host. I was able to reset the root password through the host and subsequently log in, but running passwd to reset any other passwords resulted in a segmentation fault. According to the logs, pam reported authentication failures whenever any account tried to log in using the correct password. I also saw these messages in the logs:

May 10 11:11:31 bookdslc kernel: [   89.168997] prelink[2298]: segfault at 4f3625 ip 00000000004002f8 sp 00007fff3a2546f8 error 7 in prelink[400000+123000]
May 10 11:11:44 bookdslc kernel: [  101.261034] passwd[2299]: segfault at 0 ip 000000380927f4d0 sp 00007fff48283cc8 error 4 in libc-2.11.1.so[3809200000+16f000]
May 10 11:12:05 bookdslc kernel: [  122.614483] passwd[2302]: segfault at 0 ip 000000380927f4d0 sp 00007fff6699b148 error 4 in libc-2.11.1.so[3809200000+16f000]

As the only recent update relevant to authentication was nss-softokn and nss-softokn-freebl, I checked the changelog and saw something related to prelink, so I downgraded the packages with yum. I am now running version 3.12.4-10.fc12 of both packages and authentication is working properly, with accounts that never had their password changed during the process.

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

How reproducible:

Steps to Reproduce:
1. Attempt to log in or use passwd
Actual results:
Authentication failure or segmentation fault

Expected results:
Successful login or password change

Prior to reporting this bug I could not search specifically by nss-softokn so I did not see the bug already reported.

See bugs 590190, 504949, and 590508 for the gory details. For the time being downgrading nss-softokn and nss-softokn-frebl to the previous version, as you did, is right thing to do. A fix is in the works.
