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

medium Nessus Plugin ID 19200

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.

Solution

All pam_ldap users should upgrade to the latest version:
# 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
