Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

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 :

An attacker 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.

# emerge --sync
# emerge --ask --oneshot --verbose '>=sys-auth/pam_ldap-178-r1'
All nss_ldap users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose sys-auth/nss_ldap
