Name        : pam_krb5
Product     : Fedora 11
Version     : 2.3.5
Release     : 1.fc11
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 2.3.4 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.
--------------------------------------------------------------------------------
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)
