Oracle Linux 4 : nss_ldap (ELSA-2006-0719)

Synopsis :

The remote Oracle Linux host is missing a security update.

Description :

From Red Hat Security Advisory 2006:0719 :

Updated nss_ldap packages that fix a security flaw are now available
for Red Hat Enterprise Linux 4.

This update has been rated as having moderate security impact by the
Red Hat Security Response Team.

nss_ldap is a set of C library extensions that allow X.500 and LDAP
directory servers to be used as primary sources for aliases, ethers,
groups, hosts, networks, protocols, users, RPCs, services, and shadow
passwords.

A flaw was found in the way nss_ldap handled a PasswordPolicyResponse
control sent by an LDAP server. If an LDAP server responded to an
authentication request with a PasswordPolicyResponse control, it was
possible for an application using nss_ldap to improperly authenticate
certain users. (CVE-2006-5170)

This flaw was only exploitable within applications which did not
properly process nss_ldap error messages. Only xscreensaver is
currently known to exhibit this behavior.

All users of nss_ldap should upgrade to these updated packages, which
contain a backported patch that resolves this issue.
