RedHat: Moderate: nss_ldap security update
Summary
Summary
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.
