Mandriva Linux Security Advisory MDVSA-2008:049
http://www.mandriva.com/security/
_______________________________________________________________________

Package : nss_ldap
Date : February 25, 2008
Affected: 2007.0, Corporate 4.0
_______________________________________________________________________

Problem Description:

A race condition in nss_ldap, when used in applications that use
pthread and fork after a call to nss_ldap, does not properly handle the
LDAP connection, which might cause nss_ldap to return the wrong user
data to the wrong process, giving one user access to data belonging
to another user, in some cases.

The updated package hais been patched to prevent this issue.
