Description Jose Plans 2007-03-28 09:23:36 EDT

Description of problem:

Bug with two dependancies: 
    * pam: [234308]
    * shadow-utils: [234310]

When using faillog, the IP or hostname information gets truncated with strncpy()
on the 12 first characters due to the sizeof() from its definition.

Used the 52 present in rawhide. This is just part of the problem on write, read
(shadow-utils) need change as well for faillog to read it, since both have the
same header I'm sending a parallel bug blocker of this one against shadow-utils.

Version-Release number of selected component (if applicable):
pam-0.77-66.14
shadow-utils-4.0.3-60.RHEL4

How reproducible:
Always

Steps to Reproduce:
1. Setup a pam stack to use pam_tally.so
2. Fail an authentication
3. Check with faillog
  
Actual results:
fail line truncated.

Expected results:
At least the IP address.

Additional info:
patch from rawhide.

Comment 4 Tomas Mraz 2007-03-28 09:41:17 EDT

This cannot be changed due to breaking compatibility with existing faillog files.

The correct way is to backport pam_tally2.so from RHEL5.
