[GLSA-200507-13] pam_ldap and nss_ldap: Plain text authentication leak

Vulnerability Assessment Summary
pam_ldap and nss_ldap: Plain text authentication leak

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200507-13
(pam_ldap and nss_ldap: Plain text authentication leak)


Rob Holland of the Gentoo Security Audit Team discovered that
pam_ldap and nss_ldap fail to use TLS for referred connections if they
are referred to a master after connecting to a slave, regardless of the
"ssl start_tls" ldap.conf setting.

Impact

A possible hacker could sniff passwords or other sensitive information
as the communication is not encrypted.

Workaround

pam_ldap and nss_ldap can be set to force the use of SSL instead
of TLS.
