RHSA-2006-0719: nss_ldap Vulnerability Scan
Vulnerability Scan Summary
Check for the version of the nss_ldap packages
Detailed Explanation for this Vulnerability Test
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
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
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.
