Description Somsak Sriprayoonsakul 2006-03-13 12:19:31 EST
Description of problem:

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

Recently, we faced many successful attempt of SSH brute force attack to the user
with simple username (root, oracle, etc...) and the main reason is that they all
use password with some simple pattern (such as QWERTY keyboard pattern like
1q2w3e4r, qawsedrf, etc...). I uploaded dictionary file left from their SSH
brute force program in our server with this issue.

How reproducible:
   Just try "1q2w3e4r" as password, it pass without any warning.

Steps to Reproduce:
1. Just type simple password when you change the password
Actual results:
   cracklib let simple password pass successfully

Expected results:
   cracklib should warn about patterned-password

I'm removing the Security keyword from this bug.  While this issue does have a
security aspect to it, it is not a secuirty vulnerability itself.  We reserve
the Security keyword to describe security vulnerabilities.
