This script is Copyright (C) 2004-2015 Tenable Network Security, Inc.

Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200403-12
(OpenLDAP DoS Vulnerability)

A password extended operation (password EXOP) which fails will cause
the slapd server to free() an uninitialized pointer, possibly resulting
in a segfault. This only affects servers using the back-ldbm backend.
Such a crash is not guaranteed with every failed operation, however, it
is possible.

Impact :

An attacker (or indeed, a normal user) may crash the OpenLDAP server,
creating a Denial of Service condition.

Workaround :

A workaround is not currently known for this issue. All users are
advised to upgrade to the latest version of the affected package.

Solution :

OpenLDAP users should upgrade to version 2.1.13 or later:
# emerge sync
# emerge -pv '>=net-nds/openldap-2.1.13'
# emerge '>=net-nds/openldap-2.1.13'

Risk factor :

Medium / CVSS Base Score : 5.0
