Description:
A security issue has been reported in OpenLDAP, pam_ldap and nss_ldap, which can be exploit by malicious people to gain knowledge of sensitive information.
The security issue is caused due to the client not connecting to the master server using TLS when it is referred by the slave server to the master server for password changes. This allows malicious people to gain knowlege of users' password by sniffing network traffic.
The security issue has been reported in OpenLDAP version 2.2.26, pam_ldap version 1.76 and nss_ldap 2.239. Other versions may also be affected.
Solution:
pam_ldap:
Update to version 1.80
nss_ldap:
Update to version 2.240.
Configure LDAP servers to only accept LDAPS connections and configure clients to connect using the "ldaps://" URLs.
