[SECURITY] Fedora 9 Update: pam_krb5-2.3.5-1.fc9



--------------------------------------------------------------------------------
Fedora Update Notification
FEDORA-2009-6279
2009-06-15 22:05:02
--------------------------------------------------------------------------------

Name        : pam_krb5
Product     : Fedora 9
Version     : 2.3.5
Release     : 1.fc9
URL         : https://fedorahosted.org/pam_krb5/
Summary     : A Pluggable Authentication Module for Kerberos 5.
Description :
This is pam_krb5, a pluggable authentication module that can be used with
Linux-PAM and Kerberos 5. This module supports password checking, ticket
creation, and optional TGT verification and conversion to Kerberos IV tickets.
The included pam_krb5afs module also gets AFS tokens if so configured.

--------------------------------------------------------------------------------
Update Information:

This updates the pam_krb5 package from version 2.3.2 to 2.3.5, fixing
CVE-2009-1384: in certain configurations, the password prompt could vary
depending on whether or not the user account was known to the system or the KDC.
It also fixes a bug which prevented password change attempts from working if the
KDC denied requests for password-changing credentials with settings which would
be used for login credentials, and makes the "-n" option for the "afs5log"
command work as advertised.
--------------------------------------------------------------------------------
ChangeLog:

* Tue May 26 2009 Nalin Dahyabhai <nalin redhat com> - 2.3.5-1
- catch the case where we pass a NULL initial password into libkrb5 and
  it uses our callback to ask us for the password for the user using a
  principal name, and reject that (#502602)
- always prompt for a password unless we were told not to (#502602,
  CVE-2009-1384)
* Wed Mar  4 2009 Nalin Dahyabhai <nalin redhat com> - 2.3.4-1
- don't request password-changing credentials with the same options that we
  use when requesting ticket granting tickets, which might run afoul of KDC
  policies
* Thu Feb 26 2009 Fedora Release Engineering <rel-eng lists fedoraproject org> - 2.3.3-2
- Rebuilt for https://fedoraproject.org/wiki/Fedora_11_Mass_Rebuild

  (CVE-2008-3825)

- fix license tag
* Wed Apr  9 2008 Nalin Dahyabhai <nalin redhat com> - 2.3.1-1
- don't bother trying to set up a temporary v4 ticket file during session open
  unless we obtained v4 creds somewhere
