CentOS 4 : nss_ldap (CESA-2006:0719)

high Nessus Plugin ID 36238

Synopsis

The remote CentOS host is missing a security update.

Description

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.

Solution

Update the affected nss_ldap package.
