  a bug affecting passwords that contain 8bit characters (e.g.
  umlauts).  Affected passwords are potentially faster to crack via
  brute force methods CVE-2011-2483.

  SUSE's crypt() implementation supports the blowfish password hashing
  function (id $2a) and system logins by default also use this method.
  This update eliminates the bug in the $2a implementation. After
  installing the update existing $2a hashes therefore no longer match
  hashes generated with the new, correct implementation if the
  password contains 8bit characters. For system logins via PAM the
  pam_unix2 module activates a compat mode and keeps processing
  existing $2a hashes with the old algorithm. This ensures no user
  gets locked out. New password hashes are created with the id  &qt $2y &qt
  to unambiguously identify them as generated with the correct
  implementation.

  Services that do not use PAM but do use crypt() to store passwords
  using the blowfish hash do not have such a compat mode. That means
  users with 8bit passwords that use such services will not be able to
  log in anymore after the update. As workaround administrators may
  edit the service's password database and change stored hashes from
  $2a to $2x. This will result in crypt() using the old algorithm.
  Users should be required to change their passwords to make sure they
  are migrated to the correct algorithm.");
