 Mandriva Linux Security Advisory                         MDKSA-2006:201
 http://www.mandriva.com/security/
 _______________________________________________________________________
 
 Package : pam_ldap
 Date    : November 7, 2006
 Affected: 2006.0, 2007.0, Corporate 4.0
 _______________________________________________________________________
 
 Problem Description:
 
 Pam_ldap does not return an error condition when an LDAP directory
 server responds with a PasswordPolicyResponse control response, which
 causes the pam_authenticate function to return a success code even if
 authentication has failed, as originally reported for xscreensaver.
 This might lead to an attacker being able to login into a suspended
 system account.

 Updated packages have been patched to correct this issue.
